Great writeup. This is exactly what I was looking for. The OP was right. There was never a decent writeup before this. Everyone always says, "modify your stocker," but no backing up that statement. Great DIY. Thanks.
Question, however. Would the 04-05 hood be any different than the 02-03's for underhood fitment? After all, the 04-05 STi air splitter, I think is bigger, but more so in height to fill in that giant scoop!
