What is the small hose on the front side of intake for?

[David15151]

Here is my new intake. Yes I know the thick hose is for the BOV, the smaller one is for the canister for emissions, the even smaller one is for the PCV vavle.. but whats the super small one on the front side for? I looked at my stock intake pipe and it looks like its capped off. So... why is it here on my aftermarket intake?

I think it might be used for the stock bcs like on the 1gs maybe so its universal for the 2g mas swap???? Anyway just cap it off you don't need it.

Small one on the front is for the stock boost control solinoid.
Other two are NOT FOR THE BOV but for the valve cover and other is either pvc or canister.. I forgot. niether is for the blow off valve though...

edit: sorry, just cap it off if you're using an aftermarket mbc/ebc.
