2 3/4" Upper IC Pipe - stock replacement for $149
No-MAS or "Blow-Thru" Intake Pipe Set for $199 + $60 for filters

You need a Y-pipe to solidly mount the AIT sensor into - the stock plastic one won't work so well. The MAP sensor just connects to one of the nipples on the plenum that gives manifold pressure, like the BOV line.

If you are keeping the charcoal canister hooked up on your car, specify that you want the charcoal canister tube on your front intake pipe so you can hook it up.

You probably want to do a lot more research on the AEM before you go down that path. It isn't a good choice for novice tuners. Something like a S-AFC, ARC-2, or eManage would be a better choice if you are just getting your feet wet with tuning.
