Easy to install, took me about 30 minutes, I could feel the power difference, I got 20% off plus $25 back from K-N so great price

It does what it claims. While the hp and tirque increases are modest, they make a noticeable difference in passing. Mpg has been unchanged by the mod. Clearance is kind of tight in my vibe gt because of the strut tower brace but installation is easy.
