Is it possible to tune the air/gas mixture. I built my own intake using the OEM throttle cover an just ran pipes down from there(it was a Cold air) then ran the pipes down behind the headlight....the check engine light came on. Got the codes, it was my O2 sensor. Any Body help?

Good write up. But, you might want to note that not all 2006+ cobalts have the SAI. I have a 2008 ls and mine does not have it.

If the dealer installed them the window sticker (not the original window sticker but a dealer printed one) would show them as dealer add-ons. Usualy when the dealers install items like that they put some kind of graphics on the car too (like Ecotech RS, Z61, GTX, Special Edition, etc).

If you bought the LT used they were most likely installed by the owner.

That manifold is on my list of mods to get. It is a great performance mod for the 2.2 especially for the price. However if you do not drive your car spiritedly it is a waste. The manifold is only good for your top end, and (slightly) hurtful for your low end torque. It just basically shifts your power band upward.
