It doesnt look like much I know. Im converting to a square plenum for the sake of my sanity in the next week. Its completely bolt up uses all vacuum lines and the IAC. Id need a contour zetec intake manifold though. I have a escourt manifold and a focus manifold, but you contour guys are a little diffrent from either i think. It looks like its going to be worth about 15 whp in the top with torque losses below 3000 rpms.
