      Comments about K&N Replacement Air Filter:

      I've been using K&N filters since the early seventies. Cars, trucks, motorcycles. They really are the best. Don't bother with the copy cats, they are junk. Look at the cost of a new engine it is worth the extra couple of bucks to get the real thing.
