K&N Warranty Department - A Team of Professionals Working For You

At K&N, the quality of our air filters and intake systems is something which we take very seriously. We back our O/E Replacement Air Filters and Air Intake Systems for street use with a Million Mile Limited Warranty®. If one of these K&N products ever fails or does not give you complete satisfaction, K&N will replace it. We also warrant that when used properly, these products will not cause engine damage and will not result in a vehicle warranty denial.

K&N has a team of specialists dedicated to resolving situations between consumers and vehicle repair facilities, where a K&N part is the center of concern. If a service provider ever alleges that a K&N part has caused the need for a repair, please contact K&N Customer Service to notify us of your situation.

K&N's Warranty department will work with the consumer to get their vehicle repaired in a timely manner. We will also assist service providers in determining if/how a K&N product failed, so that they can make an accurate repair diagnosis. We even reach out to the next generation of repair technicians by working 1-on-1 with top automotive trade schools, equipping their students with knowledge about K&N products and "urban myths" which we have proven false.
