I know that this was brought up a million times already but there are no definite numbers anywhere. I would really like to buy the injen intake but i would like some numbers to make sure. My other choice would be a K&N typhoon. What do you guys think? I have the GMPP Stage 2, GMPP Performance Exhaust, and some new spark plugs.

 

9 out of 10 order the INJEN. They now have a perfect fitment, and are a bit cheaper. Also INJEN claims more gains.

 

and it looks the best IMO

 

Injen is the only way to go. I have no cel lights and the SS/SC screams like a jet taking off. Your cobalt will turn heads with the intake. i ordered mine from turbo tech. great price and it fit great. A++++++++++++++++++++++++++++++++++++++++++++++
