grendel i'm not sure if that intake will work, they prolly just want your money. i got an adapter off ebay before and it didnt even fit my car. it was supposed to be specially made like that one...
also take a look at this pic
i dont think that intake will work because that red tubing at the top has to go somewhere, and there is no place for your IAT sensor to plug or screw into (note the part with the two screws on the intake). if you dont have that plugged in your car may not work right.
