"I only use K&N air filters because they allow 4 times the amount of air to the engine than a paper filter and the K&N filter is a lifetime filter, good for about 100,000 miles or so and then you just clean, re-oil, and re-use. I have six vehicles, all equipped with K&N and I plan to use K&N air filters in the airplane I'm building as well, for the same reasons. An engine that breaths better with K&N is a happier engine." —Robert L from Bedford, TX bought a K&N Air Filters for a 1993 BMW 5-Series.
