on the stock intake system there is the valve cover vacuum that i must make a nipple for on the turbo intake side and then there is the iacv and some other larger(.5" diameter) vacuum source going into the stock intake right next to where the iacv goes. which do i need to make nipples for on my cold side of the turbo? i know i need the iacv but do i NEED the other one(dont know what it's called) right next to it in the stock location??
