My 2013 Chrysler 200 Convertible responded as I hoped by using this filter. Gas mileage increased, although I don't know how much yet. The only trip we took with it so far was a convertible run of about 225 miles through Arkansas mountains with several Corvettes. I was able to stay with them and yet average 28 mpg for the day. Have used your filters before in my 2008 Chrysler Pacifica and have always been happy with its performance.

I was impressed with the difference in how my car accelerates and it seems to run better.

Took less than 5 min to install, simply unscrew the air filter cover, and replace with the KN (33-2470). Added more pick up, gas milage, and I noticed quicker acceleration.  A must have for anyone who cares about their car, simple as that.
