my mods are listed below and i just dynoed 214rwhp/287rwtq....but that is without my explorer intake setup i have sitting in the garage....another mustang at the dyno with pretty much the same #'s as me ran ~9.30 in the 1/8th....
An aftermarket upper/lower intake won't do much without heads, cam and bigger injectors, etc etc etc. Lots of ways to spend your cash, and unless you pick it up for $100 or so, it's not really worth it.
