If you really want to put that intake to use, scrap the acessport and go opensource. Im guessing you have AP v2, should sell for like 550-600 bucks. Find your self a opensource tuner in your area, and go from there. Tune should be ~200$, and the cable for it is maybe 80-90 used off your local forum. Go and search. BTW, youll make profit of return on this...
BTW, if you dont by chance have a tuner in your area, then go check out
Its a opensource "race" tune. Again, another opensource product. I have the standard stage II map from them, and its great. And only 52 dollars. That race map will cost you 77. BUT if you sell your AP for 600, you can afford the tune, the cable, you have the intake, the boost solinoid, the STI or better top mount, and the fuel pump. It will be loads better than your cobb map. Tuners name is Braden, lives down here in Texas, and is a great guy, and helped me alot when I was having some issues. Turns out it was just crappy Houston weather. But he helped me reguardless with many PMs back and forth.
But, best thing to do is research research research. Figure out what you want for the car. You have several choices, go make the best
