I replaced the stock type paper air filter on my 2008 Mazda 3 with a 33-2293 K&N replacement filter.  What I noticed from the first time I drove it with the K&N filter was a noticeable increase in throttle response and acceleration. This was at all throttle openings, but particularly at smaller throttle openings.  On top of this, mileage is a little better (1 MPG or so) than with the stock type paper filter.

Always a fan of K&N air filters. Definitely adds boost to acceleration. I had a 2002 Mazda Protege that I had to scrap, but one of the things I took out of it was the 8 year old K&N air filter that I maintained. It was still in great shape. I gave it to another Protege owner.

Its the last air fliter you will buy for your car. My car is breathing a lot better.
