Should our 930 cars have pop off valves installed? I know it's common for SCs to have them and haven't heard talk about this for a 930. I wouldn't think it's needed cause our air intake system is different being a turbo, but I'm not sure. So it a good idea to install one? Or is it not needed?

I was helping a friend with his SC and it back fired and I now know what you guys are saying about it blowing up the air box. He has a pop off valve installed, but if he didn't it wouldn't have been pretty.
