Stuart Greene, Oak Park, Illinois
Instantly noticeable increase in pep, take-off and engine strain noise (reduced) in a high mileage VW Jetta that just had a new air filter placed 6 months previous. Second K&N filter owned on my vehicles and I cannot say enough positive about them. The hype is not an exaggeration.
