From the manufacturer
How Does a Cold Air Intake Work and Why Should I Replace the One That Came With My Vehicle?
In a standard air intake system, air passes through a disposable paper filter and then flows into the engine through a complex system of tubing. K&N cold air intake systems provide a less restrictive path for airflow, increasing the volume of cool, oxygen-rich air into your engine. A performance air filter is paired with specially designed tubing and a custom air box or heat shield (engineered to protect the intake air from the heat of the engine), which in combination deliver a guaranteed increase in horsepower and torque.
Legendary K&N Quality & Reliability

---|---|---|
Increased Horsepower & Torque- GuaranteedYes, K&N intakes really do increase horsepower and torque; in fact, it's guaranteed. Each intake kit undergoes significant testing to help ensure that the air filter and intake tube are positioned to deliver large increases in airflow and horsepower. |
Less Restriction = More Engine GrowlBy removing excess stock baffles, you get to enjoy a satisfying engine growl on acceleration that returns to quiet once at speed. The amount of growl is all in your hands… or should we say feet. Growl while accelerating on the open road and return to quiet as you drive through your neighborhood. |
Proudly Made in the USAK&N products are designed and manufactured on-site, and all of our Cold Air Intakes are made in the USA. K&N is headquartered in Riverside, California, and also operates facilities in Grand Prairie, Texas. Our US based, knowledgeable customer support staff is available to assist you with any questions or concerns. |
No Substitution for the Original- The Difference a K&N Filter Makes in Your Vehicle
Increased performance starts with K&N’s reusable, air filter, which combines layers of pleated, breathable cotton with K&N’s signature red filter oil. Paper air filters, while efficient, can become quickly clogged as their pores fill with dirt and debris. K&N’s oiled cotton filter absorbs dirt and dust particles rather than physically blocking them. The tacky, oiled particles that collect in the filter become an asset to the filtration rather than an obstacle, capturing new particles entering the system while still allowing a high volume of airflow to pass through. This allows clean air to continue flowing into your engine.
Unlike disposable paper filters, which typically last for 12-15,000 miles before they must be replaced, the high-performance K&N filter included with your intake can go up to 75,000 miles before needing to be cleaned (under normal driving conditions).
K&N Cold Air Intakes- Frequently Asked Questions
|
|
|
|
---|---|---|---|
Why is Dyno Testing Important & How Can I Tell if It’s Accurate?K&N's air intake horsepower/torque testing is performed at our in-house facilities in Riverside, CA on wheel-based dynamometers and help provide a power estimate that is likely to more closely reflect real-world conditions than an engine-based dynamometer. K&N’s standard testing is designed to measure relative power differences on a vehicle with and without K&N products installed, and SAE (Society of Automotive Engineers) correction factors are utilized to help ensure accuracy. If you notice horsepower claims from other manufacturers that seem too good to be true, we encourage you to do your own research. Check the dynamometer reports for vehicles, dates tested, and if correction factors are used. |
How Does a K&N Intake Protect Your Engine?Most disposable paper filters create a large amount of airflow restriction, as the openings in the filter media have to be extremely small to filter efficiently—which slows airflow. Because dust accumulates on the surface of the disposable filter and blocks the openings in the media, the filter will typically become increasingly more restrictive to airflow over time. Conversely, K&N oiled filters are engineered to become more efficient over their recommended service life as dirt and contaminants are integrated into the filter media, while still allowing a high volume of air through to the system. This allows you to continue to get the performance you expect from your K&N intake, while also being able to rely on the cutting-edge efficiency and protection that a K&N oiled air filter provides. |
What's the Difference Between a Roto-Molded and an Aluminum Intake Tube?Both a Roto-Molded and an Aluminum Intake Tube from K&N provide the same increase of air flow to your engine. It all comes down to how you want it to look in your vehicle. If you enjoy a more custom look under the hood, the Aluminum Tube is a great choice. |
What Does the Heat Shield Do and Is That Better Than a Closed Air Box?Both the custom heat shield and HDPE air box help protect the incoming air from the heat of your engine. They both have unique features and which one you choose is a personal preference based on those features. High-performance drivers may want an open filter element and heat shield for even greater airflow. Off-roaders may prefer an intake system with a custom air box, which helps protect against dust, dirt, and moisture and offers additional filter protection from extremely dirty environments or water crossings. Options with an enclosed air box give you the freedom to adventure while offering easy access to the air filter for quick cleaning and maintenance — no special tools required. |
Easy to Install
Installing an intake kit might seem intimidating, especially if it's your first DIY car modification, but thankfully you don't have to be a seasoned mechanic to successfully install a cold air intake yourself. While every kit is slightly different (since they are designed to be a perfect fit in the engine bay of specific year/make/models), installation can typically be completed in 60 minutes or less and requires only simple hand tools. Detailed, step-by-step instructions are included with each kit.
Tools Typically Needed for Installation
- Ratchet
- Extension
- 10mm socket & 14mm socket
- Allen key
- Flat blade screwdriver
- Phillips screwdriver
- 10mm wrench
- Pliers

There was a problem filtering reviews right now. Please try again later.
I do want to leave a comment for anyone thinking of getting this or any cold air intake kit. There are people that will scoff at these indicating that it isn't possible to gain any efficiency or performance simply by installing one of these. Aside from the well documented proof that cooler air is more dense and therefore capable of providing more power, having a breather element and tube that reduces restriction DOES help. No, it doesn't 'add' horsepower but it does reduce the amount of effort the engine has to use (taking away horsepower) to inhale. Case in point - grab a plastic coffee stirrer and a soda straw. Put the stirrer in your mouth and breathe ONLY through the stirrer. Run around the block. No do the same thing with the soda straw. THAT is what these provide. Don't expect miracles. Don't expect to double your horsepower. DO expect the engine to run a little more efficiently which does give measurable gains in mileage and horsepower.
Reviewed in the United States on October 25, 2018
I took my time installing, utilized all the sealing material, trimmed to fit perfectly and double checked my work...net result, zero rattles, perfect fit (almost, see below), and per my butt dyno, the claimed power gain is at least close which is unusual for a CAI, usually the cool sticker is about as effective. It seems some real thought and engineering went into this, it also tells me the stock setup was fairly restrictive. As another reviewer pointed out, the plastic tube reduces the chance for heat soak, and the heat shield is effective. I hemmed and hawed at dropping the $$'s on a CAI, but it turns out you get what you pay for, this time in a good way.
As for sound, it's stock quiet at idle, a little louder (in a good way) in normal driving conditions, and obnoxious at WOT. At WOT I like it, my GF hates it, 'nuff said.
The fitment caveat, kit comes with a replacement crankcase ventilation hose to replace the stock piece, it is about 6" too short, and half the diameter so you will be buying that elsewhere. Maybe why Amazon claims the kit doesn't work?? Otherwise, it's a perfect fit, but you'll need the 5/8's hose. Overall, very happy

However, when it came to installing the K&N intake housing onto the intake manifold, that’s when things started to get tricky.. Reference the picture attached.
Also, after certain amount of mileage driven with it, a part of the intake housing cracked from one of the mount brackets and where the mass air flow sensor is located. (Reference other pictures)
I believe it was caused by vibrations but still you would imagine getting a good quality pvc plastic cold air intake for the price you pay…
I purchased this last April 2021 and already all kinds of damages
K&N should probably rethink on how to improve the quality of this product

Box contained everything it needed and the filter works great.
I can already feel an increase in power in the lower end and the engine sounds great when you put the pedal down!
K&N has always been my go to for CAIs and filters and I don't see that changing anytime soon.
