KN Replacement Air Filters

K&N’s replacement air filters are designed to increase horsepower and acceleration while providing excellent filtration.


K&N makes over 1,200 different replacement air filters for virtually every vehicle on the road.

These filters are washable and reusable and are custom designed to fit into your existing factory air box. Their drop-in design means adding performance is simple.

With most vehicles you simply remove the disposable air filter and replace it with a K&N.

Their stock replacement air filters for street vehicles are covered by their famous K&N Million-Mile Limited Warranty™ and will be THE LAST AIR FILTER YOUR VEHICLE WILL EVER NEED.

K&N Million Mile Limited Warranty® and Consumer Protection Pledge
K&N warrants its street vehicle OE Replacement Air Filters for one million miles. When used properly and found to be defective, return your filter and the receipt from purchase and K&N will replace it free of charge.

K&N’s Consumer Protection Plan goes one step further than its Million Mile Warranty. The performance aftermarket has, at times, been plagued by car manufacturers and automotive dealers that may attempt to discourage you from customizing your vehicle. They prefer you buy OE parts and not modify your car or truck and have even been known to void their own manufacturer’s warranty due to vehicle modification. When you buy an OE replacement K&N High-Flow Air Filter or High-Flow Air Intake System you can be confident your vehicle’s warranty will remain in effect.
