On the backside of the plenum (facing the drivers fender) theres a plug there. Any idea what that was meant for? It would be a perfect location for a manifold air temp sensor for my ms setup.

Its 3/4" npt, right?

3/4" NPT is HUGE. Are you sure?

NPT dimensions refer to the inside diameter of the pipe fitting. If the hole is 3/4" in diameter I would guess that it is 3/8"? but you should take the plug with you to Brafasco or something and have them identify it to be sure.

Whoopsy, brain fart, yeah 3/8" npt, I was thinking 3/4" because thats what the size of the hex nut on the sensor I was thinking of using.
