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.

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.

I replaced my car's original paper air filter with this K&N air filter when I noticed the engine light on. The old filter was dirty with grime and small pieces of flowers. As soon as I started the engine after installation, the engine light cleared and the engine is running smoothly. I knew this filter would work well since I have one installed in one of my motorcycles for a couple of years. I installed it in my 2007 Mazda CX7 and it is a perfect fit.
