I started buying the HP type of OIL FILTER to go with the KN AIR FILTER I purchased online LAST YEAR.  These products are better than any other brand on the market in terms of performance.

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.
