I only use a K&N oil filter for my 2002 Ford Ranger. If I had to pay twice as much compared to a regular filter, I would still get it no matter what I am a K&N customer for life Nothing else comes close to these filters I trust the high quality design for dependability and performance.

I really like these oil filters much more than the white K&N filters I normally purchase. They seem to do a better filtering job than those white filters

K&N Oil Filter; Billet
  • Billet Aluminum Housing
  • Washable and Reusable
Eric, Albuquerque, New Mexico
Lightning fast processing, professionalism, and shipping. Very pricey yes, but what you are buying is an engineered product of exceptional craftsmanship that sets it apart from everybody else. When I opened it I could see where the money went. Dumb proof 4 piece design, with top grade seals on each piece. Almost seemed like it had a set torque in it going onto the engine block, you can't mess it up. Less pressure drop and better filtration is a no brainer, and I got my money's worth. Haven't cleaned it yet, but i won't mind it for better performance.
