Okay, I put on an injen airtake and everything went great. When looking at the finished product I noticed that one of the hoses had a hole in it now. Probably from me moving it around.. it was very stiff. It says vac pipe and an arrow on it. It just so happens that there's a hose that came with the injen airtake that is the same size as the broken hose. Is this what it is for? I reread the directions like 5 times and it says nothing about this hose. Idk what else it would be for.
