Just got the car and pretty new to having a turbocharged car. Had a Supercharged Cavalier before so this is all new to me and trying to learn a few things. Now to the question, this is one thing I saw that I need to get replaced (pics included) but not sure what it's called or for that matter what it even does. If anyone could help that's be great. The car is a 2010 SS Cobalt Coupe. Thanks
