"There is a lot I want to do to this car to improve its performance, this was a great place to start. A very simple investment in the K&N filter made a noticeable difference in the overall performance of my vehicle. A small increase in power, better (smoother) transition between gears and gas mileage as gone up." —Robert H from Dublin, OH bought a K&N Air Filters for a 2007 Mazda CX-7, 2.3L 4-cyl. engine.
"This K&N filter is great. I had it for about 2 weeks and can already notice difference. Not that it added extra mileage, but i can feel extra horse power too. Thanks AutoAnything for fast shipping too, I had it at my door in a couple of days." —Ivan M from Aurora, CO bought a K&N Air Filters for a 2007 Mazda CX-7, 2.3L 4-cyl. engine.

"The mileage has improved about one mile per gallon and the low end torque seems to have increased minimally." —Gordie S from Cleburne, TX bought a K&N Air Filters for a 2007 Mazda CX-7, 2.3L 4-cyl. engine.
"After reading reviews and comments on a Mazda discussion Forum, I replaced my stock filter in my Mazda CX-7 with the K&N filter. I could see right away the difference in quality of material between the stock filter and K&N.
What I didn't expect was the vast improvement in mileage. I just got back from a 200 mile trip, and after calculating my mileage, saw that it went from 19MPG to 24MPG...big difference (especially when I have to use premium fuel).
Can't beat that for return on investment...
