Hi everyone. New to the forum and don't have the ats yet. I will be getting a used one this weekend. 3.6 performance. I've been informing myself on the Issue with the catch can. I see that the 2.0t require it but I see that's it's not just a 2.0t problem. Apparently it's the 3.6 engine from gm. Should I worry about putting one on the 3.6? I also have a buick lacrosse 3.6 for my wife and they carry the same engine. If i need to put one on the ats then I'll need to put one for my lacrosse. Thanks in advance.
