Ross Davis, Peoria, Illinois
 I've been using K&N filters for 20 years and have never been disappointed. I always recommend K&N Filters to everyone.
Christopher Rief, Morganton, Georgia
 The part was shipped right away and fit perfectly in the car
Sonia Gamer, Milford, Pennsylvania
 Recieved product in under a week. For my Subaru it was as easy as unlocking the latches and replacing the filter. Seemed to already make a difference.
Lindsey Andrews, Denver, Colorado
 Great filter. So much better than the paper original. I get almost 10% better mileage over my old filter. Given that the old filter was fairly dirty this does not surprise me. Better engine response than before as well. A must have for your vehicle!
Shaun Helbig, Australia
 I have a K&N in my truck so it seemed like a good idea to put one in my wife's car.
Mike S, Addison, Illinois
 Couldn't believe how restrictive the original equipment air filter was . After installing the K&N replacement , the motor seems smoother and more responsive . The great gas mileage of my Subaru appears to have improved also .
