K&N Air Filter Warranty Information

K&N Million Mile Limited Warranty®

Million Mile WarrantyK&N O/E Replacement Air Filters and Air Intake Systems are backed by a Million Mile Limited Warranty when used primarily on paved roads and on vehicles for which they were designed. If one of these products ever fails to provide complete satisfaction, K&N will replace it.

Any K&N Air Filter used for 1: any type of racing or competition; 2: any off-road use, custom or modified applications; 3: any off-road or dual sport motorcycle/ ATV use; 4: any illegal highway use, marine, or industrial applications. All K&N Air Filters not covered by our million mile warranty are warranted against defective materials or workmanship for one year from date of purchase with no mileage limitation. This includes K&N Air Filters sold for ATV’s and off-highway or dual-purpose motorcycles.

K&N Air Filters should be cleaned every 50,000 miles for highway use, more often in dusty conditions. Cleaning should be done with K&N cleaner and air filter oil (or comparable air filter cleaner and oil). Use of compressed air, or chemicals not designed to clean and re-oil cotton air filters (gasoline, transmission fluid, motor oil, lightweight oil, or diesel fuel) will void the warranty. Any damaged, abused or modified K&N Air Filters will not be warranted.

Any K&N product returned to K&N must be sent at customers' expense along with proof of purchase. Call 1-800-858-3333 or contact K&N by email or mail.

Register your warranty at our web site and you'll be eligible for special promotions and product upgrade opportunities.

Any defective K&N Air Filter properly returned to K&N will be replaced. K&N will not be responsible for any other expenses incurred by the customer under the terms of this warranty, nor shall it be responsible for any damages either consequential, special, contingent, or otherwise; or expenses or injury arising directly or indirectly from the use of the K&N Air Filter. K&N reserves the right to determine whether the terms of the warranty, set out above, have been properly complied with. In the event that the terms are not complied with, K&N shall be under no obligation to honor this warranty.
