    intake manifold help


    if i remember right this is the cold start valve where does the vaccum line go?

    Yup, either cold starting valve or air boost valve, the vac. line goes along the back of the plenum, goes to intake tube, close to t/b.

    EDIT: IMO, if I were you, I'd block it off, def. not necessary in CA at all, or anywhere else really!

        ^As far as emissions, that wouldn't affect it at all I don't think, the valve is for quicker starts in colder climates, many of the JDM motors have block plates from the factory. As far as a visual inspection, they'd have to be pretty good to spot that. But hooking it up is pretty easy, so it's not a big deal either way.

            On my H series plenum, I have 6, it's small things like this that will tend to differ, no real default setup sometimes.
