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. That sounds un-American to us, which is why K&N and the Magnuson-Moss Warranty Act protect consumers from such denied warranty claims. 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. If you experience a difficult dealership, K&N will resolve the issue so you won’t have to. The following summarizes the K&N Consumer Protection Pledge:

K&N pledges to our customers that they will not be taken advantage of and charged for a repair due to a dealership warranty denial blamed on the presence of a K&N product.
