I am making a new aluminum intake pipe. I need to buy an aluminum bung to weld on to the pipe for the IAT sensor. I know the sensor threads are pipe thread. Do anyone know what size NPT it is and also where to find a place to buy the aluminum bung. I think I found some on ebay, but I don't know if there is a better place. I am also a little confussed on the NPT size because I know the sizes run a little weird (eg. you dont just measure the thread dia. like that of a regular bolt thread). Any help is appreciated.
