This will work just fine with the 75mm size plenum. This is a cast piece, so there will be some casting flash and rough areas in the runners. It will not be completely smooth. Having said that, the runners are much smoother than the outsize textured finish.

This manifold is designed as a bolt-in replacement for all 1999-2004 4.6L 2V Mustangs and uses the stock alternator and all other stock engine accessories.
You should be just fine.
