The engine is stock nothing is done to it, what would i need to buy to put the blow off valve and for it to work okay?
You already have a blow off valve on your car if your driving a GS-T. Please be more clearer on what you want to do here. I'm assuming put on a new Blow off Valve.
Yeah we need some more information on the subject...I think I know what you are talking about, but I wanna make sure before giving my opinion.
