      I am returning this product, disapointed

      from Prescott, AZ

      Verified Buyer

      Comments about K&N Replacement Air Filter:

      After installing (approx. 50 miles), 'Check Engine Light" illuminated. I brought the vehicle to the dealership where I purchased it new. A certified technician diagnosed the issue as "oil from the K&N filter contacted the Cold Air Intake sensor, which caused the 'check engine light" to illuminate.
      I was told that subsequent damage to the engine resulting from continued use of the K&N filter would void my warrantee.

      As a result, I am returning the K&N filter AND requesting reimbursement for service charges for diagnostic fee (see repair order).

            I HAVE USED THIS PRODUCT IN ALL MY MANY VEHICLES THROUGHOUT THE LAST 15 + YEARS. THEY ARE FAR FAR SUPERIOR IN DESIGN AND CLEAN AIR AS WELL AS A FEW MORE AVAILABLE 'HP' AND 'MPG'. MY CHEVY 2500 HD DIESEL 6.6 TURBO CALLS FOR A $68.00 ONE TIME USE FILTER....ITS A NO BRAINER! AND EVEN BETTER IF YOU HAVE A DISCOUNT COUPON :)

                  • Q:

                    this filter appears to be about 1/2 inch to long to fit into my stock airbox - everything I can find says this is the correct filter for my application. Is there a trick to fitting it?

                      A:

                      If the air filter does not fit correctly, I recommend taking the air filter back to the store where you bought it. Take the receipt with you and see if the right air filter can be found for you.
