Im pretty new to the sport compact thing but im learning and it seems to me that if you just mate a good cone filter directly to the throttle body then remove the piece of metal that blocks up the hood scoop on the rs you should essentially have a cold air intake minus all the piping. the only problem i can forsee is the hoses coming from the valve covers and the intake manisfold. i have a solution and that is to tap a hole in the top of the filter and then run all the hoses to it. if there are any flaws in my thinking i would appreciate the info. i really dont want to spend 200+ dollars for a cold air if i can get the same results from a 50 dollar filter and some engineering.
