    port matching intake plenum and intake manifold

    would there be any gain in port matching the intake plenum and the intake manifold, i have a pathfinder plenum with a 60mm tb on it right now.

    I doubt there is much difference between the plenum and lower intake. But I know the lower intake and heads often do not line up perfectly.

    Anytime you match up your ports on anything, there is a gain to be had.
