This is my 4th or 5th KN Filter and 2nd Cold air performance system using on several vehicles. I am very happy every time Currently using 33-2057 on my 1996 Impala SS. Nicely boost in power, and gas mileage is flawless, seeing near 30 mpg highway and 17-18 city on a high performance lt1 350 and a 4200 lbs car. I'm a KN customer for life... Thanks

When I put the air filter into the car I noticed that I had a little more power when asking the car to speed up quickly. Thank you for this great product.

Thank you so much! I didn't realize I had to change the filter every 30,000 miles. My 2003 Jeff Gordon car just hit 36,000.....the change actually makes the care run a little better....though it normally does run fantastic. Thank you

I have had this filter on my car for a little over a year. The most important thing that I have seen is the increase to my fuel efficiency. Not to mention the fact that the increased horsepower isn’t that bad either. With that said I have to admit I was wrong and I am now a believer of the claim that K&N makes they are not some empty comment it is a fact that my wallet can prove.
