Revive your K&N Cold Air Intake with a K&N Cold Air Intake Replacement Filter. The heart and soul of your cold air intake is the filter, and an oiled cotton-gauze K&N Filtercharger is guaranteed to restore your system to its former glory.
By reducing restrictions, K&N filters boost horsepower, torque and throttle response. And while your K&N filter is busy letting the power in, it’s keeping engine-killing crud out. Deep pleats and tacky oil trap the dirt—multiple media layers let the power-producing air flow right through.
Washable and reusable for life, your K&N replacement filter could be the last filter you buy. Better yet, get an extra replacement filter to make scheduled cleaning even easier. While you’re cleaning one filter, the other’s in the vehicle, ready run.
Designed to fit any K&N Cold Air Intake, these replacement filters also fit other brand intakes—so upgrading to the World’s Best Air Filter is a snap. Best yet, your K&N Cold Air Intake Replacement Filter is backed by a Million Mile Limited Warranty.
Our 40+ K&N Cold Air Intake Replacement Filters customer reviews have an average rating of 4.50 out of 5 stars. To see specific reviews about your vehicle, please select your year, make and model from the drop down above.

Looks really cool in my engine compartment and sounds great when I lay on the throttle. Can't say I noticed and performance or gas mileage increase. Im going to add a throttle body spacer and see if that helps .The fact that it is reusable and looks cool makes it worth the purchase.

I have been using K & N Filters since 1971. When I learned they made a cold air intake for my car, I was ecstatic. I purchased a spare filter for the intake so I can always keep a clean one on while I clean the other. With K & N Filters, I know my car is safe and receiving clean air the engine requires. They are easy to clean and mount. Do yourself and vehicle a favor and purchase a K & N filter. You'll be glad you did.

I bought a replacement filter to swap out my original filter from my K&N Cold Air Intake. I changed Filters and cleaned the old filter with the K&N Recharge Kit. I use my Truck in harsh conditions. After a good clean i now have a spare ready for the next swap. Great filters

Ordered my replacement K&N Filter and it arrived quickly and was very well packaged. It was the exact fit for my vehicle and was easy to install. AutoAnything has great prices on top of line products.

It is a little loud when you get on the gas. Very easy install, less than 30 min. I also added a cat back exhaust, (50 flow master). Combination of both is very aggressive, but sounds and performs great. In cab noise is not too bad.

I bought the K&N 63 Series AirCharger High-Flow intake kit for my 2006 Toyota Tundra 4.7L V8 truck. Part number at that time (year 2008) was #63-9027. I have been very pleased with the performance of this K&N product. Now I am interested in purchasing a replacement unit for the one installed in the vehicle. Will you advice me on which filter to buy that will adequately replaced the one installed, while the later is cleaned? Thank you in advance for your prompt response.

would this air filter affect a new car warranty? I bought one but have not installed it? It is a lot smaller in thickness than the original? Why is that?
Answered by Nathan S. — Feb 20, 2013 8:57 AM
Hi, According to the Magnuson Moss Warranty Act, a vehicle manufacturer cannot void the warranty of your vehicle due to an aftermarket part unless they can prove that the aftermarket part was the cause or contributed to the failure of the vehicle (15 U.S.C. 2302(C)). It’s always best to work with a performance-oriented dealership, but no matter who you choose, you’re protected by the law. The K&N filter is thinner than you stock filter because it traps contaminants within the media unlike paper filters that rely on sheer surface area to filter.
