I just got my TB compliments of Supercoupes Unlimited. Do I need to gasket match the plenum to the TB. There is a recess for the IAC but not on the MP plenum. Thanks again gents.
if you look at the tb there is a machined recess around that IAC hole that opens up into the main opening of the TB. That will let it breathe when you attach the plenum. Look at the stock TB it looks the same and will work just fine
