Se monte parfaitement sur ma voiture. Je n'ai pas senti pour l'instant une augmentation de couple ou de puissance.

I’ll admit that I was skeptical, that an air filter could/would help boost horsepower. Well, you can believe this or not, but I actually have a different car, since installing my new K&N Air Filter. The boost in power was shocking to me. The day I installed my new K&N Air Filter, I had my oil changed and supplied my mechanic with a new K&N oil filter. When I left the shop, I ran the car on a back road and I could tell a difference. However, when I got out on I 75, South of Atlanta, at one point, I looked down and realized I was going 92 MPH. Sure didn’t feel like I was flying. LOL My car was smooth as silk. (I have a 2007 Honda Civic EX Coupe with 170,000 miles) I was already averaging 42 mpg BEFORE I had my K&N products installed. I did some serious figuring, and my mileage changed from 42 to 46. Not that much, but considering I can fill my car up for $22 and go almost 500 miles on one tank of gas.......yeah, I’m happy with that K&N products are freakin awesome.

High hopes for this air filter. My civic does seem a little more peppy. Had to adjust how I push on the gas. Prior to install I was getting 39 mpg. First tank with the K&N air filter I got 34 mpg. On my second tank now, will let you know how that goes.
