Do Cold Air Intakes Really Work? Before And After Dyno Test

/3 Comments/in /by

Performance claims are one thing. Backing those claims up is quite another. At CAI, we believe in real power testing. And only ever make real power claims.

But real-world testing by our customers is the only way to back up these claims. In this blog, we cover the installation of one of our cold air intakes into a brand new Z71 Chevy Silverado by Street Speed 717.

Check out the video below.

The Plan: More Power

Almost as soon as they had bought it, Street Speed 717 decided to treat their brand-new Chevy Silverado truck to one of our cold air intake kits. With just 433 miles on the clock, they headed out to DiabloFormula Racing to do some pre-install dyno runs.

Standard Spec Dyno Runs

The 2017 Chevy Silverado was bone stock with no modifications and still factory-fresh when it was strapped to the dyno. Factory figures of 355hp and 385lb-ft of torque are claimed. As with all manufacturers, those are measured at the crank, so a dyno run will always show lower numbers.

That said, the 5.3-liter V8 produced consistent figures over three runs with a best of 297hp and 334lb-ft at the wheels. Impressive results, but they were keen to see just what kind of improvements our CAI cold air intake could make. To restate, the original “before” test setup was:

  • Three consistent runs
  • Truck was totally unmodified
  • Best result of 297hp and 334lb-ft at the wheels

The Install

Within minutes, Andy from DiabloFormula Racing had removed the stock intake. Our kits provide everything you need to fit the intake straight out of the box. Every sealed intake kit we sell has the following features:

  • OEM- spec fasteners and connectors
  • Original sensors are retained
  • Inspection window to check reusable air filters
  • Powder-coated aluminum parts to reduce intake temps
  • No tuning needed

The CAI intake was soon fitted, and the Silverado was ready for the next set of dyno runs.

Cold Air Intake Dyno Runs

The benefits of installing a cold air intake include lower fuel consumption and improved intake sound. But the reason most people use our kits is for the increase in power.

“Final word is you can say that this intake will net you about 15 to 20 horsepower and same thing for torque. We are confirming REAL gains on a dyno here.”  – Mike, Streetspeed717

The first run immediately showed an improvement of 15hp and 9 lb-ft over the best figures achieved with the stock intake. After a short break, they reran the dyno, and this time they got 24hp and 17lb-ft above the stock numbers.

  • Three consistent runs
  • No reprogramming or modifications – just a CAI intake
  • Best result of 321hp and 351lb-ft to the wheels
  • Improvements of 7.5% in power and 5% in torque
  • Torque curve was smoother

No tuning, no modifications, and the exact same weather conditions. The added benefits of improved throttle response and a meatier intake sound are just icing on the cake. But not every cold air intake will deliver these kinds of results. It takes years of development and testing, which CAI does on all their cold air intakes.

Get The Best Cold Air Intake In The Market For Your Truck

“Honestly was expecting 10 to 15 – at the wheel especially – we got 20 [at the wheel] and 25 torque. Especially [impressive for] a truck because unlike a car it’s running through a transfer case which cuts down on the power and it has a much longer drive shaft, bigger wheels, bigger tires, and a bigger differential. So, to make that much horsepower in a truck – compared to like a Camaro SS – is amazing.”  – Andy, DiabloFormula Racing

Metal vs Plastic Intakes: Pros And Cons

/in /by

When it comes to enhancing the performance of your vehicle’s engine, upgrading the cold air intake system is a popular choice among enthusiasts. One of the key decisions you’ll face is whether to opt for a plastic or metal cold air intake. Each type has pros and cons, but metal cold air intakes offer a better solution for achieving optimal engine performance.

Read on as we explore the pros and cons of both options and explain why metal intakes are the best option. 

Plastic Cold Air Intakes

plastic cold air intake

Plastic cold air intakes are a popular accessory on many aftermarket auto part websites. These intakes are easier and cheaper to manufacture, typically using a rotational molding process. This process creates parts by pouring hot, liquid plastic into a mold that rotates, filling the void. While this process is inexpensive, it produces lower-quality parts which vary in thickness and can create air turbulence or reduced air optimization that can hinder any potential performance gains.  

Pros:

  • Cost-Effective: Plastic intakes are generally cheaper to manufacture, resulting in a lower price point for consumers.
  • Lightweight: Plastic intakes are lighter than their metal counterparts, which can contribute to overall vehicle weight reduction.
  • Insulation: Plastic helps insulate against engine heat, preventing heat transfer and maintaining a lower intake air temperature.

Cons:

  • Durability: Plastic can be more susceptible to cracking or breaking over time, especially when exposed to extreme temperatures or mechanical stress.
  • Heat Soak: Plastic intakes may suffer from heat soak, where accumulated engine heat affects the intake air temperature, potentially reducing performance gains.
  • Limited Airflow: Plastic’s structural limitations may hinder airflow optimization, limiting potential power gains.

Metal Cold Air Intakes

Metal cold air intakes offer a range of advantages that make them a superior choice for performance-oriented drivers. While they are typically more expensive than their plastic counterparts, better performance gains and a more durable and longer-lasting product more than offset that cost. Typically made from aluminum or stainless steel, they are better at shedding heat and can help dress up your engine bay.    

Pros:

  • Durability and Longevity: Metal intakes are highly durable and less prone to damage, ensuring a longer lifespan and sustained performance.
  • Heat Dissipation: Metal efficiently dissipates heat, minimizing the risk of heat soak and maintaining a consistently cooler intake air temperature.
  • Improved Airflow: Metal intakes can be designed with smoother contours and larger diameters, enhancing airflow and potentially increasing horsepower and torque.
  • Engine Bay Aesthetics: Metal intakes often provide a polished and premium appearance that enhances the visual appeal of the engine bay.

Cons:

  • Cost: Metal cold air intakes are generally more expensive due to the higher manufacturing and material costs.
  • Weight: Metal intakes are heavier than their plastic counterparts, which may have a marginal impact on overall vehicle weight.

The Superiority of Metal Cold Air Intakes

CAI intake

Metal cold air intakes offer a clear advantage over plastic counterparts in terms of durability, performance, and overall value. The ability to dissipate heat efficiently, maintain consistent intake air temperatures, and optimize airflow can significantly enhance engine power and responsiveness. While they may come at a slightly higher cost, the long-term benefits and improved performance make metal cold air intakes a superior investment for serious enthusiasts seeking to extract the most from their vehicle’s engine.

How To Install A CAI Cold Air Intake On A Chevy Silverado Trail Boss

/in /by

One of the first things you probably did when you bought your new Silverado was to find a little open road and rev it up to hear that engine roar. If you love to hear that sound and feel your truck respond with lots of horsepower, you should consider a cold air intake. When you install a cold air intake on a Chevy Silverado, you can immediately hear and feel the difference it makes, plus you’ll notice additional benefits as you drive it longer. In this article, we’re featuring YouTuber Chase at LMFSCREW and hearing what he thinks of the Cold Air Inductions cold air intake he installed on his 2021 Chevy Silverado Z71 Trail Boss (with a 6.2L engine). Check out the video below:

CAI Cold Air Intake Install: Step-By-Step

As you can see in the video, replacing a factory air filter with a cold air intake system is relatively simple. Here’s a quick breakdown of how to install a cold air intake on a Chevy Silverado:

silverado cold air intake
  1. Disconnect the negative terminal of your battery – for safety’s sake.
  2. Disconnect and remove the factory PCV hose and snip all connecting zip ties.
  3. Disconnect your mass airflow (MAF) sensor.
  4. Pull the top/lid of the factory air box (the bottom is retained in place) out, as well as the factory air filter.
  5. Remove the MAF sensor from your existing air tube, being careful not to damage it. Install it in the new air tube.
  6. Install the inlet elbow onto the throttle body and attach the PCV hose.
  7. Insert the air filter into the top of the filter box housing, after removing the protective sticker from the plexiglass window.
  8. Install the intake tube onto the filter and loosely tighten the hose clamp.
  9. Install the top of the air box and tube and tighten bolts, hose clamps, etc.
  10. Connect your MAF sensor and snug all bolts throughout.
  11. Reconnect the negative terminal of the battery.

Why Replace The Chevy Silverado Factory Filter?

silverado cold air intake

As Chase mentions in the video above, the factory filter is not the worst out there – so why should you replace your factory air filter and install a cold air intake on your Chevy Silverado? It’s not like it’s an ugly factory unit to begin with…and it technically does work fine. So why bother?

First, a cold air intake increases the volume of air entering your engine and ensures it is cooler air, both of which increase your engine’s power. Whether your truck is a few years old or brand new, it’s nice to get a little more power out of your engine when you can. Using our 6.2L cold air intake kit, you can expect gains of 12-14 horsepower. This kit can also be used on 2019, 2020, or 2021 Silverados or GMC Sierras, in addition to several popular 2021 SUVs.

If you drive a truck, your top priority probably isn’t gas mileage (or you’d be driving a Prius instead). But if you can improve it with a simple tweak, why wouldn’t you?

“We all know about horsepower and torque…you get used to it…[but] you always want a little bit more. This thing is going to be absolutely sick!”  – Chase, LMFSCREW

Swapping out a stock air filter with a cold air intake system can increase your fuel efficiency by a few miles per gallon, which is always a plus when you regularly drive a larger truck, like the Trail Boss. Or, if you’ve modded your truck similarly to what Chase explains in the video. When you upgrade wheels and tires, you usually add some weigh. An intake can help with the extra work the engine will need to do as a result of those few extra pounds.

“Overall, it’s just a solid intake…I mean, it looks really good I don’t think we’re gonna see any negatives from it – only positives.”

How To Increase Chevy Silverado Fuel Efficiency

/in /by

You’re not alone if you’re wondering how to improve a truck’s gas mileage. After all, that’s one of the biggest downfalls of owning a truck. Most of them aren’t super friendly on your bank account when it comes time to fill the tank. In a way, that’s the unfortunate price of admission. If you want the benefits of a big truck (e.g., towing, ground clearance, power), you have to deal with less-than-optimal gas mileage.

While modern fuel-efficient trucks are getting better in this area, there are some ways to increase Chevy Silverado fuel efficiency, even in an older model.

5 Easy Ways To Increase Chevy Silverado Fuel Efficiency

There are several ways to tackle the fuel efficiency problem that most trucks experience. None of them will be miraculous – they won’t double your Silverado’s MPG – but if you combine them, you can achieve a noticeable difference for your Chevy. If you use your truck daily, you know it’s all about the small gains that, when combined, create long-term results.

1. Basic Maintenance

One of the easiest things you can do to increase Chevy Silverado fuel efficiency is just to maintain your truck well. When you keep up with basic maintenance (i.e., changing the fluids regularly, keeping your tires properly inflated, keeping air filters clean, etc.), your truck can perform more efficiently.

2. Install A Cold Air Intake

Swapping out your stock air filter with a cold air intake system will definitely make a noticeable difference in your truck’s gas mileage. (Check out CAI’s Silverado 1500 cold air intake kits here.) This system pumps a higher volume of cooler air into your engine, which increases the oxygen content and produces a cleaner, more efficient combustion cycle. In the video below by YouTuber Lonestar Hawaiian, you can see how he intends to tackle the MPG problem with his 2007 Chevy Silverado – by upgrading to a Cold Air Inductions intake system. Check it out:

In the video above, you saw that Lonestar Hawaiian was installing a cold air intake on his 2007 Chevy Silverado, aiming to increase miles per gallon. With his 2020 Trail Boss (which he already updated with a CAI cold air intake), he noticed a significant increase in fuel efficiency (16.5 to 21 mpg).

“When I installed the Cold Air Inductions intake on the 2020 trail boss I was really impressed with the quality of product, the fit and finish, and actually the performance that came out of it.”  – Lonestar Hawaiian

And remember Item 1 above – “Basic Maintenance?” With a CAI intake system, you get a clear, plexiglass window to monitor how dirty the air filter is and see when it needs to be recharged with a CAI Cleaner and Recharge Kit. It’s a win-win.

3. Reduce Drag

Most people don’t realize how much drag an average pickup truck creates when it moves down the road. This friction with the air makes the engine work harder. Installing a tonneau cover over your truck bed is one way you can reduce the drag on your truck. It will help you be a little more efficient. Plus, it keeps your gear or cargo secure and dry.

4. Use An Engine Programmer/Tuner

You can use an engine tuner or programmer on many modern vehicles, including the 5.3 or 6.2L Chevy Silverado. Keep in mind that when you purchase a vehicle from a dealer, the engine is programmed to perform at a level that will appeal to a broad audience. Mainly providing:

  • Soft, smooth shift points. Most drivers prefer this over quick shifts, even if faster shifts improve performance.
  • Fuel systems that are optimized to maximize fuel economy and minimize emissions, even if such settings lessen performance.
  • Shift points and fuel maps are both tuned for stock air intake and exhaust systems.

This little plug-in computer can help you dial in how you want your engine to run to increase fuel efficiency or power – especially if you’ve made modifications.

5. Slow Down

Yeah, it’s obvious and probably a little annoying to hear, but it’s true. When you hit the gas to hear that beautiful engine roar (especially after installing a cold air intake or aftermarket exhaust system), you’re consuming much more gas than if you reasonably accelerate. If you want to see a boost to your fuel efficiency, take it easy on the gas pedal – you’re probably not on a race track. If you are, well…then let her rip.

If you’re ready to install a superior cold air intake on your truck, trust Cold Air Inductions for the highest quality intakes. CAI is a Tier 1 OEM supplier manufacturing cold air intakes since 2004. CAI intakes are made from the highest quality materials and crafted right here in the USA, delivering real power and great quality. Shop Cold Air Inductions online or contact us today!

Camaro SS Intake Install By Hammerdown Motorsports

/in /by

Cold air intakes are an inexpensive way to increase your vehicle’s performance while improving its sound. However, not all intakes are the same. The key is finding a high-quality system that cools and improves airflow. Otherwise, installing an aftermarket cold air intake may do more harm than good.

That’s why Hammerdown Motorsports chose an intake system from Cold Air Inductions. In this post, we’ll cover the highlights of their video and explain why you can count on our cold air intakes to improve the performance of your car or truck.

Cold Air Inductions 2017 Camaro SS Intake Install

camaro cold air intake

In this video, Hammerdown Motorsports installs a new Cold Air Inductions intake on their 2017 Chevrolet Camaro SS. Previously they installed an aftermarket exhaust with long tube headers, so the cold air intake complemented that mod.

Right off the bat, they were impressed with the quality of the Cold Air Inductions intake system. They liked the build quality and appreciated the details, like the spacer between the intake and throttle body, which creates a vortex to improve the airflow. Overall, they found it easy to install and thought it noticeably improved the sound of the Camaro.

“We’ve showed people what this thing really puts out – horsepower wise…it’s pretty impressive in my eyes. They really do make a helluva intake – I mean – it looks so professional…that’s exactly what everybody wants. This [intake] looks so nice and clean…like it came from factory like that.”                                   – Andy, DiabloFormula Racing

The Performance Is In The Details

There are many great-looking air intakes on the market, but nothing matches the performance of our intake systems. That’s because each kit is designed and tested to fit a specific vehicle and provides a tight fit to keep the engine compartment’s hot air out of the intake.

“Obviously, you have to go to the aftermarket to get the care and detail [like you get] from a company like Cold Air Inductions. Definitely recommend this for anybody with an LT or LT4 engine. They make all kinds of intakes for every different make and model so definitely check them out.”                                                     – Hammerdown Motorsports

Additionally, each system comes with the following:

  • High-quality, reusable eight-layer cotton fiber air filter
  • Plexiglass inspection window
  • OEM-spec tubing for the crankcase breather tube

It only takes 15-20 minutes to install one of our cold air intakes, but you’ll immediately notice the improved power, sound, and fuel economy.

Why Choose A Cold Air Inductions Product?

“We got [the CAI intake] installed here – it’s got the nice plexiglass window on the top to see if your filter is dirty or anything like that. It’s got the heat insulation inside the box make sure you’re not getting the hot air blown into your engine. Really, this thing is something that you would expect to be on a car like this – you’d think that maybe even the factory would have something like this.”  – Hammerdown Motorsports

At Cold Air Inductions, we do real power testing that shows actual power gains. Every one of our kits is built to the highest quality. We use OEM-quality fittings and retain all original sensors. CAI kits include:

How To Install A GMC Sierra Cold Air Intake

/in /by

If you’re reading this, you’ve probably at least entertained the idea of installing a cold air intake on a truck. To be honest, why wouldn’t you? It’s relatively cheap, it doesn’t take a lot of time or experience to do yourself, and it offers several benefits for your truck. Because of that, a new cold air intake to replace your factory air filter is one of the first modifications every truck owner should make. This article will focus on how to install a cold air intake for a 2021 GMC Sierra, but you can find plenty of other installs for other makes and models on our site or YouTube channel.

Check out the video above to see YouTuber Donslife walk through the process of installing a cold air intake on a 2021 GMC Sierra AT4 (6.2L engine). As you’ll see, it’s a smooth operation and results in a much better sounding, looking, and performing truck.

Cold Air Inductions Intake Kit

CAI intake kit

The specific Cold Air Inductions kit discussed in this video (Silverado and Sierra truck air intake) comes with all the pieces you’ll need for the installation. That includes the air induction housing, air filter element, PCV tube, inlet duct, and aluminum air intake tube. It’s compatible with 2019-2022 GMC Sierras with 6.2L V8 engines. Don had this to say about the construction of the CAI intake:

“About the construction [of the intake] – being aluminum, it’s less susceptible to heat soak. Plastic components tend to soak up a lot more heat so this [intake] is going to keep the air a lot cooler which means better efficiency and more power for you. Also the air filter element is not something you’re going to pick up off the shelf in an auto parts store. It’s very custom and it’s engineered to get the max air flow.” – Don, DonsLife

The beautiful part about this install is that Don is adding this intake to a truck that already has a Borla S-Type exhaust installed. Viewers get to see the results of combining a premium CAI intake with an upgraded aftermarket exhaust – a result worth watching – and hearing!

Benefits Of An Upgraded Cold Air Intake

GMC intake kit

The video discusses several of the benefits of installing a CAI cold air intake, primarily:

  • You can generally expect a 12 to 14 horsepower improvement after the GMC Sierra cold air intake is installed. You’ll also see a 2 to 3 mile per gallon improvement in gas mileage, on average. That’s always a perk when you drive a truck.
  • As you see in the video, the process is simple to do and doesn’t take a lot of time. If you have the right tools and 30 minutes to spare, you should be able to swap out your factory air intake for a new cold air intake with no problems.
  • Another perk that the video cited is that the design of our cold air intake utilizes the bottom of your truck’s air intake box so it’s an easier install and forms a nice, tight seal.

GMC Sierra Cold Air Intake Installation Process

Here’s the basic process for removing a factory air intake on your truck and replacing it with a high quality cold air intake from Cold Air Inductions:

  • For safety reasons, disconnect the battery terminal. This will also help reset your system.
  • Start the removal by disconnecting the existing PCV hose (using the push tabs).
  • Disconnect (not remove) the mass air flow (MAF) sensor.
  • Loosen the resonator and remove it from the throttle body.
  • Remove the top of the factory air box (making sure to save the screws) and remove the factory filter as well.
  • Remove the MAF sensor from the removed housing, being very careful with it. Install it into the new aluminum air intake tube supplied with our kit.
  • Attach the intake duct to the throttle body and loosely tighten it using hose clamps. Connect the PCV hose as well.
  • Insert the air filter element into the top of the air box (removing the protective film first). Insert the aluminum air intake tube into the filter element, and move it into place in the engine. Connect the aluminum air intake tube to the intake duct.
  • Tighten all hose clamps and screws.
  • Reconnect the MAF sensor harness.
  • Reconnect your battery.

It might look like a fair amount of steps, but the cold air intake installation process goes very quick. With a little mechanical experience and the right tools, you’ll be hearing your truck’s engine come to life with a new voice in no time.

DiabloFormula Racing Installs CAI Intake And Gains 14 RWHP

/in /by

There’s no doubt that a quality cold air intake is one of the quickest ways to boost your vehicle’s performance, intake sound, and even improve fuel economy. But with so many systems out there it can be tough to know which one is best for you.

Sometimes you have to rely on the stats the manufacturer provides. But not every cold air intake is tested the same way. And real world performance doesn’t live up to the claims.

That’s why Cold Air Intakes does real power testing that results in real power gains. But don’t take our word for it, check out this video of DiabloFormula Racing installing one of our products and decide for yourself.

The TrailBlazer SS Cold Air Intake Install

DiabloFormula Racing has had some great results from Cold Air Inductions intakes in the past. So much so that they became a vendor for the brand. And seeing as they know just how good CAI cold air intakes are, Andy ordered a full intake kit for his girlfriend Steph’s Trailblazer SS.

Vehicle Specs

  • Chevy Trailblazer SS
  • 394hp 6.0-liter V8 (when stock)
  • K&N Air Filter
  • Rebuilt transmission
  • Stall converter
  • Modified headers and pipes
  • Upgraded cam

As a testament to how quick and easy the install is, Andy decided to do the entire job on a freezing day out in the snow. While it was snowing. Try that with a any other competitor’s product.

Cold Air Intake Kit Details

CAI intake

Every Cold Air Inductions kit comes with everything you need for a hassle-free install. And every component is built to the highest standards. We use OEM-quality fittings and keep all original sensors.

Andy also mentions the different styles of intakes available from CAI, with the option to go with a chrome or satin black finish:

“Personally I think the satin black finish looks better – it just looks cleaner because the inside of the engine bay is black and the cover is black – so that’s why we went with the satin black.”    – Andy, DiabloFormula Racing

CAI intake kits feature:

  • An inspection window to check reusable air filters
  • Powder-coated aluminum parts to reduce intake temps
  • Air boxes designed to maximize cold airflow
  • OEM-spec fasteners and connectors
  • OEM sensors are reused

The Install

CAI intake

“[The CAI intake] is a simple set-up. It literally took 10 minutes to do.”  – Andy, DiabloFormula Racing

To start with the Mass Airflow Sensor (MAF) is disconnected. The plastic engine cover is removed and then the original plastic intake cover is unscrewed. The Trailblazer already had an older K&N air filter installed which Andy removed. He also took out the screen from the MAF to further improve airflow.

The next step was to place the CAI filter and housing into the engine bay. Andy was surprised at just how easily it slotted into place. Bolting it down took just a few minutes and then it was time to fit the piping and connect it to the intake manifold. Then the vacuum hose was fitted, the MAF sensor reconnected and the plastic engine cover screwed back on.

The entire installation process took just 10 minutes. And the only tool required was a screwdriver. Not bad for an upgrade that delivers 14 rear-wheel horsepower, and improves the intake sound and fuel economy.

Sealed vs. Open Intake Air Boxes – Which Is Best?

/in /by

A high-quality cold air intake is a great way to add extra power, enhance intake sound and even improve fuel economy. At Cold Air Inductions we offer a range of great induction kits for many makes and models. But which one is right for you?

That’s the question we’ll be answering in this blog as we examine the pros and cons of our sealed and open intake air boxes.

Open Intake Air Boxes

An open intake air box design does not enclose the air filter completely. It offers more airflow than an OEM system as well as an improved intake sound. This design is the one many of our first-time buyers choose. That’s because it’s the easiest way to add more power and torque to your vehicle. Our universal fit intake kit is the perfect solution for anyone looking to upgrade their OEM intake system. Features of our LS/Coyote Universal Open Intake Kit include:

  • Engineered to maximize the airflow
  • Universal fit – Works on any LS/Coyote engine with a slot-style mass airflow (MAF) sensor and 4-inch outer diameter throttle body
  • Can be configured in several ways, making it easy to fit into most engine bays
  • OEM quality fit and finish levels
  • Includes thermal-coated tubing to limit heat soak
  • Fits several popular crate engines and swap motors – including the 5.0 and LS

Closed Intake Air Boxes

A sealed or closed air box design shields the intake system from the hot engine compartment. Our sealed air boxes are much larger than standard, to fit a larger air filter. We use insulated aluminum and more efficient tubing to enhance engine efficiency and boost performance. The gaps that normally occur around a stock heat shield or a weather strip seal are not an issue with CAI’s closed systems as the air filter is completely isolated from the hot engine compartment. Features of our closed intake kits include:

  • Inspection window on certain kits – great to check the reusable air filters
  • Powder-coated aluminum components for long-lasting performance
  • Perfectly insulated air boxes to reduce intake air charge temps
  • Precision TIG welding, OEM-spec fasteners and connectors
  • OEM sensors remain in stock

True enthusiasts understand the benefits of an upgraded intake like those designed by CAI. Cold Aid Inductions Inc. is the leading manufacturer of sealed air box intake system for the 2010+ Camaro. HorsepowerJunkies.com even named Cold Air Induction intakes the “Best” air intake around. But, the final decision between an open or closed air box design comes down to what you want from your air box.

Whether open or closed, all CAI intakes replace the restrictive stock air tube with a more efficient tube. The air box is fed cool air through the same channel from the front grill that fed the stock air box. The important features to remember are:

Open Air Box Designs:

  • Offer improved sound over a closed OEM intake system
  • Tend to be more cost-effective than closed systems
  • Add more visual flair under the hood than OEM system
  • Can be affected by hot engine temperatures
  • Are very easy to install

Closed Air Box Designs:

  • Offer higher performance gains than open-box design
  • Are easy to check the air filter with handy inspection window
  • Improve economy and intake sound over an OEM system
  • Ensures intake air is kept cool thanks to the sealed design
  • Can be pricier than open air box option
  • Offer OEM quality and look

The Research And Development Process At Cold Air Inductions

/in /by

When it comes to performance cold air intakes, you don’t want the same old heat-absorbing plastic system. You want a durable, solid (yet lightweight) system with an overall design that will keep the intake air cool as possible. That’s where CAI cold air intakes excel.

CA intake systems feature high-performance air filters, thermal-coated tubes, and insulated air boxes. All these parts are designed to specs above and beyond the industry standard. Our intake development process starts with CAD engineering. We use the same development tools employed by automotive manufacturers, but we don’t stop there. Read on to learn all about our R&D process, and why the end result is a step above the rest.

The Start: Design

Our process starts with a review of the original equipment manufacturer’s (OEM) air intake. We test it to identify flow restrictions and gauge how they impact mass airflow sensor readings. We examine the size and spacing of the OEM components and measure the airflow and air intake temperatures. Using what we learn, we develop a mathematical engine performance and efficiency model to guide product development. This becomes our blueprint for product development.

Up Next: Development

The next step is to prototype several potential designs and complete preliminary testing. The goal of this phase is to identify the best prototype. Once the best prototype is found, we then refine the design based on performance testing results.

While our exact testing systems and procedures are proprietary, we can share the three main types of tests we run:

  • Air Flow Restriction Testing: We measure airflow in several standard conditions (e.g., idle, 1/2 throttle, WOT, etc.)
  • Thermal Testing: We measure the temperature of the air flowing into the engine
  • Engine Performance Testing: We measure fuel flow and engine torque

Once a winning prototype is developed through the testing methods above, it’s time to start engineering.

As you can imagine, the test results depend upon one another. When airflow restriction decreases, or temperatures drop, engine performance will improve. Understanding the interdependence of these tests is one of the keys to our success. They provide the tools and data to model airflow and engine performance in a way that few other companies can match.

In fact, Cold Air Inductions is one of the only companies selling aftermarket air intakes and is also a Tier 1 OEM supplier. When automakers need a performance air intake designed, they call CAI.

Building It: Engineering And Manufacturing

The winning prototype then transitions into a mass-produced product. This stage involves turning the prototype into a digital model and developing tooling needs. The first few units off the line have to be rigorously tested. We’re not just ensuring the product performs like the prototype – we’re also focused on durability, fitment, and quality.

The Final Step: Production

Once the production samples meet our quality and performance standards, full-scale production begins. We start marketing the product on social media and alert our dealers about the upcoming product release. We also fine-tune the installation instructions and produce installation videos.

Throughout the entire process, we emphasize:

  • Reducing airflow restrictions to maximize performance
  • Minimizing heat soak. The air going into the engine should be as cool as possible for maximum density and performance
  • OEM grade fit, finish, and function. All CAI products are durable, easy to install, and trouble-free

Remember, Cold Air Inductions is a Tier 1 OEM supplier. As such, we have to follow a very rigorous design, development, and production process. The result? Guaranteed optimal fit, finish, and performance.
