"This is my third K&N air filter. They are still in my other 2 cars and working great (2001 Expedition, 1992 Merc Capri XR2). Nice to not have to worry so much about pressure drop and perfromance degredation as with a paper filter. They are easy to clean and re-oil (done it on the other 2 cars now)." —Edward Z from Fairfield, CA bought a K&N Air Filters for a 2003 Mazda 6.
