Very impressed with this product. There was an instant improvement and response in every way and in every gear on my mazda cx7 2.3 DISI turbo.

Best air filter ever! Have it in my motorcycle as well as my car. I can hear and feel the difference in both! Definitely worth the money!

This is my second purchase (33-2279). First was put in my Subaru Forester. The performance boost was well above my expectation. This one is in my wife's Mazda CX7, which is turbo charged. The power increase startled her! Well worth the money.
