The threads in my SuperRam for the IAT sensor are all jacked and need to be retapped, does anyone know what size tap I need to use? I believe it needs a 3/8" pipe tap but I want to make sure before I screw it up worse.

IIRC is 3/8" NPT
If you can't clean the threads up ,tap it 1/2" NPT and use a brass reducer bush

Just a quick FYI:
