Excellent product!

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.

I can definitely say that this product is worth every penny. I have noticed an improvement in fuel economy and with a turbo charged engine that's very important. I would recommend this filter to everyone.
