Is the injen intake on your website that is listed for the sc/sc 2.0 liter actually for the car? The dyno sheet doesn't seem to match since it only gets 120 hp maybe. The confusion also comes from injens site since it lists it for the SS but has the 2.2 liter. Any help you can be would be appreciated.

http://www.injen.com/7024_mkt.html is for the 2.2 Cobalts.
