K&N Replacement Air Filter is rated 4.6 out of 5 by 71.
Rated 5 out of 5 by from Easy to install. The K&N air fiwas easy to install. I noticied a increase in gas mileage,increased horsepower. Plus, i don't have to buy or replace another air filter for ten years or 100,000 miles. Plus these are green filters. There is no waste going to the landfll every year,like the paper filters.

Rated 2 out of 5 by from Good product, but did not do anything for my vehicle. Good product, I like the fact that it was safe and easy to use. But I did not see any difference in my Miles Per Gallon (MPG). I decided to give this a try since I was changing out my air filter anyways. Im glad I tried it atleast I know my MAF sensor is clean.

Rated 4 out of 5 by from Noticed a faster acceleration. The low end was definitely much better but as far as MPG I did not get any difference. Good product, wont know how good it actually keeps dirt and debris from engine until I check on it in a couple of weeks. Really easy install on my 2007 Chevy Silverado New Body Style.
