kkk seriously though you are going about it ass backwards for one, number 2 there are a couple different intake options availible, ITB and cosworth(with inlet mod), ass backward is if your talking about a stock n/a there are more primary things you do and change before even considering a different intake, and btw there are FI conversions making 260whp with the stock plastic intake....i.e. if it made that much of an performance impact you think a guy who spent 3-4k on a fi system to squeeze thier engine would of change the intake also if it was such a weak link....food for thought good luck and have a nice day.
