I am a skeptic of testimonial claims, HOWEVER, the results from the replacement of the standard paper filter with the K&N filter(the only change made!) were immediate and dramatic. The onboard computer in my BMW 840Ci is very accurate and has provided me the proof of 15% better gas mileage, plus the feeling of better performance! I couldn't believe the mileage improvement. I have gone more than 60 miles further over two tankfulls of 89 octane gas. I am a believer and am buying my brother a K&N filter for his Mini Cooper S.
