Million Mile Limited Warranty

K&N O/E Replacement Air Filters and Air Intake Systems purchased from Authorized Dealers 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.

What Is Not Covered By Our Warranty

Any K&N product 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.

Incorrect Cleaning or Use Voids Warranty

K&N Air Filters should be cleaned every 50,000 miles for normal 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 specifically designed to clean and re-oil cotton air filters (i.e. 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.

Replacement

Any K&N product returned to K&N will need a Return Goods Authorization number and must be sent at customers' expense along with proof of purchase. Call 1-800-858-3333 or contact K&N by email or mail.

Product Registration

Extent of Warranty

Any defective K&N Air Filter properly returned to K&N will be replaced. 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. K&N will not be responsible for any indirect, consequential, special, contingent, or other damages.
