More power and better response.

Very noticeable power gain and I gained 3 to 5 mpg, when I can keep my foot out of it. It is well worth the investment. It really wakes up the 2.0 PZEV motor. The customer service is the greatest, I had to contact them and they handled my problem very quickly and got me the right parts the first time. I can say they know what they are doing.

This was the 5th K&N COI I have installed in various cars an trucks. Fairly easy to install. Quality product. I will install more of these in the future. Both of my grown sons are now believers in these systems.
