Hi guys, I am thinking about making a cold air intake for my cherokee, but as i was checking it out today to size up the project, i realized i have vacuum lines on the stock air box. I know one goes to the TB, i want to say another is some type of breather, no idea what the 3rd is. Does anyone know what exactly they are, and if i would be able to bypass them, or re-route them on the new intake?
