A cheap alternative to the pipe is to cut off all the pleated except the one closest to the TB end of the sotck hose. Then take a 3" long 3" ID pipe, exhaust pipe is fine, and you can paint it if you want, push it into the stock hose (with the hose nipples for the IAC, IAT and crank case vents), then put a 3" rubber connector on the other and to connect it to the MAF. I did this for a buddy with a 3L, and it works awesome. It'd cost you maybe $8 to do, and works just as well as the aftermarket pipe and maybe better as it has the sotck connections still intact.
