Now I have a 2009 Pontiac g5. It's has the exact same 2.2L ecotech motor as in the chevy cobalt of that year but I'm posting my question here in hopes of more people can help me. I was interested in thinking about some basic mods for my car, like a cold air intake and a better exhaust system but I'm really not so sure. It's an automatic, and that alone is enough to turn me away, but are any mods worth installing on this car? Is the power gain from these mods going to outweigh the money and effort put into it? Or should I just save my money and get an '04-06 Acura RSX with a 5-speed manual that has a lot more potential for the mods I mentioned earlier and then some??
