The car runs better than before. We haven't checked the MPG yet, but we are sure it is getting better because it is running easier than before. Some people say K&N filters are bad because the oil gets on the mass air sensor and throws off codes, but that has never happened to me or my wife. We use the aerosol re-oiling can instead of the tube, maybe this makes the difference. Anyway we are very satisfied.
