Customer Feedback

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.

Ordered this as an immediate replacement of the stock air filter on a new Mazda CX5. The filter was delivered as expected and fit as expected, After years of doing business with K&N for products for other vehicles we have owned, we are not suprised.

I have always been pleased with K&N products, for my vehicles. I have not been able to make the 1 Mil. mile claim yet, but I'm working on it. I would like to see more products for foreign made auto models, such as Audi, Mercedes Benz, etc. Such things as Cold Air Intake Systems, not just filters.
