Noticed the difference in my 2007 Pontiac G5. Very happy with my purchase.

Air filter for the car was simple to install. After installing the product I notice that I would pick up speed faster than before. I say about three additional horsepower. Honestly I enjoy driving my Chevy Cobalt much more since I installed my brand new air filter. I definitely recommend this to anybody who is looking for such a product.
