Just wondering why certain blow off valves, such as the GReddy Type-S have two nipples for vacuum lines. They are not even for the same kind of hose, one is for about 6mm and the other is for 4mm. I am running a type-s on my car and have always wondered what the other small one did because I have never had it plugged to a line...
