I got my type s for 70 bucks. And i bought the Upper Intercooler piping for 20 bucks. It was flanged for 1st gen and type s. I would rather have the extra 120 bucks for other mods. The bov's do pretty much the same thing.... No i you cant flange to stock. You're goin to have to get upper intercooler piping. But either way the will increase air flow that much more.
