Works amazing in my 04 Chevy Cavalier. Noticed differences in acceleration, and fuel economy. Gained 2 mpg in the city and 6 mpg on the highway. Very good investment. No more down shifting on a larger grade hill. Easy install.

Well first off, I'm amazed with how much good this filter does for me and my older car, which is a 1999 Cavalier. It saved me time and money and of course the hassle to drive back and forth to get another disposable air filter. I gotta say for being 20 yrs old and having a heavy foot, that air filter sure does do what it's supposed to, plus my oil filter I purchased from k&n also. Thanks K&N for creating such astonishing well known products.   Sincerely, Your Valued Customer

I am a customer of K&N Engineering, and last summer I bought a kn filter for my 97 Chevy Cavalier 2.2L engine. As it is, these cars get really good gas mileage. I held on to my money after I bought this filter for my car, because you don't ever have to replace it again. EVER!!!!. So I knew right away that I wasn't going wrong with a washable and reusable filter from the world's best air filter and oil filter company, and I wasnt loosing anymore money. This filter has increased mpg and horsepower. My car now has more bit of kick to it when I get on the throttle. I gotta say that the oil filter and air filter are both A+++++++++++. Thanks KN for making incredible products.
