If I had to look for a complaint...the pics in the directions r black and white with black lead arrarrows to direct installation. The arrows in some instances blended into the pics. That's my negative. Directions straight forward, ez to follow. Installation time roughly an hour. Results, noticeably faster acceleration and nice sound increase during acceleration. I don't know what it does for mileage because I didn't check but I got what I was looking for as far as performance.
Just bought this intake, installation takes about 1-2h. Very easy, everything fits. Driving impression: Loud, i mean very loud,also no increase hp observed%X85MPG no change, I bought this because of the previous experience (second car, second K&N), also reviews of Auto Anything web side,advertise returns are easy!! 100% satisfaction guarantee... Make sad story short, AA told me to FO because my k&n was installed and used.And does not meter that is used for 3 days.Thanks AA!
