If you're talking about the nub on the left there's supposed to be a vacuum line there. You can see it on alohasurftoad's pic. That's for AT cars though. You have an MT, so you don't have that line and the nub needs to be plugged (at least that's how it is for the N55s). The MT charge pipes don't have that nub.
