I cannot figure out what this valve thing is for on the front of my B16 Vtec manifold. It is the same thing that is on the 92' Integra manifold. I looked it up on the dealer parts list and is says "valve, air boost". Does anyone know what this is for? I don't have a manual for the older integras that use the same thing. I am running an accell DFI and want to eliminate all the unneccessary crap.
