aftermarket cobalt SS
im thinking about getting a cobalt SS 2.4 and i was wondering where is a good site or company for aftermarket stuff like for the engine, interior, exterior etc. I have looked on ebay they have a few but jegs dont have anything that i could find.
I seen a chip that you suppose to put in them and get 7-10 mpg more and 18hp more does that actually work? I dont know much about new vehicles and would it hurt the comp. or engine. Thanks
