      Comments about K&N Replacement Air Filter:

      After having a K&N air filter in my previous vehicle I decided to buy this one for my 2003 Ford F-150. Immediately I can tell the performance difference between a cheap paper filter and the K&N. Looking forward to many more years of use out of this air filter.

      Noticable difference as soon as I put the filter in. Works great, direct fit. My 2000 Expedition idels much better, accelerates easier and I've even noticed about a 10% gas millage increase. Highly recommended for all cars.

          It was for my 1999 F150. Should be exact fit for each engine model.

        • A:

          I believe it is. I've used this filter in an 02 F150 5.4L and an 06 E250 4.6L, and saved quite a bit of money on reg filters.

          Yeah. You don't have to change anything for it to fit.

        Are there replacement gaskets for around the base of this filter, or is it just a one piece unit? I have had it for about 8 years.
