You guys are Magicians!!!!!! I put a K&N air filter into my '08 Honda CRV and I know that the filter vs paper provides only a couple of horsepower, but the difference in responsiveness is uncanny!!
Jeffrey Greentree, Mechanicsville, Virginia
I've used K&N air filters in my last four automobiles, (a 2002 Honda Accord, 1999 Ford Explore, 2011 Highlander and 2014 CR-V,) plus two for my son's automobiles. Although I can't quantify their performance accurately, I think they improve both performance and mileage slightly. This is important to me because I now own two four cylinder cars and want all the horsepower I can get.

I own a Honda Cr-v and it was stock, lacking that extra power that an 18 year old young man like myself wants in his ride. Baseline for my SUV, considering it only has a 2.0 litre 4 cyl. was probably about 120hp. After I dropped in a k&n panel filter I saw a decent gain in power, acceleration and smoothness. That was all fine and dandy but when I took it one step higher and put in a new metal intake system and toped it off with a K&N cone filter I saw a power increase of nearly 20hp. a LARGE increase in acceleration, and not to mention my little 4X4 Honda 4 cyl. sounds like a Z71 chevy V8. I cleaned the throttle body out, and that completes my intake modification. I would recommend K&N to anybody who cares about their ride. Thank you K&N, you rock.
