Abbott high flow delivery pipe question

[XAAMOTTOMAAX]

On the silicon hose which connects the pipe to the throttle body, there is some sort of extension and hole coming out of the pipe. What is this for? There was nothing in the same spot of the stock setup that would obviously connect. Should I plug this hole? There has to be some purpose for it being there.

If your original delivery pipe has nothing attached to it, you shall plug the hole with a screw(round head and tighten with an allen wrench) supplied along with the pipe. I think the hole is only use in certain markets to connect something for emission purpose.

Hope this helps.
