im selling my car and i need to sell all of the aftermarket stuff. i have an rsm 62mm tb f/s off of a 2005 cavalier (2.2l ecotec). not sure if it will work on a cobalt's eco but i dont see why it wouldnt. im asking $100 for the tb along with the trade of your stock tb.

 

as far as i know all the cobalts are drive by wire , and use a different tb
