So I got my ITR TB yesterday and went to install it... ok the first thing I noticed is that I am missing in the ITR a connection for a hose.. it's on the top of the stock TB..
I installed it but left that hose hanging.. is that hose important?? why is the plug missing in the ITR TB??
Tks.

(sorry for the double post here and on the NA forum, is just that nobody answers me over there... tks!)
