"I have a mazda6 2.3L, and I decided it was time to change the stock filter. I ordered it online and received it within 3 days of ordering it! It took me less than a minute to install it, and immediately after I could fell the difference in acceleration. Mileage hasn't improved much, but then again I drive mostly in the city so it won't be significant enough to notice." —Kunal C from Framingham, MA bought a K&N Air Filters for a 2005 Mazda 6.
