Rest assured with the lifetime warranty
All air filters, accessories, cleaners, and everything you can purchase at K&N Filters come with a no-hassle, lifetime limited warranty. This protects your products from any defects in workmanship or materials. If you find any, they will replace or repair your filter or product free of charge. You save on the full price of the item, even if you used a K&N Filter discount code to save on your initial purchase.
This warranty is good for the lifetime of the product (not your lifetime). To make a warranty claim, go to the website and then click on “Warranty” under “Support.” There you’ll find all the links to get in contact with K&N Filters and start the process of returning your product to get a replacement or to get it fixed.
