Not sure what your set-up is, but some of us re-located it from the stock manifold to post IC/pre-throttle-body. Less heatsoak.
As for what thread size, just take it to a hardware store that carries metric and find a nut that will work. It's metric, but not pipe thread.
If I get a chance to get down to my shop I'll try to find my old OEM IAT and see what size it is...
