The K&N Air Filter does indeed add some ooomph to any vehicle. Does add Horsepower, but what I like most is in my 08 VW Jetta, which has a manual transmission, shifting is much improved. Lot less jerky movement - SMOOTH!! I haven't noticed much of a change in exhaust tones - but does feel cleaner n smoother. Gas mileage has increased slighty. I think ALL cars should come factory tuned with a K&N filters!
