Or 3/8 NPT for GM style sensor. if no IAT is needed do the 3/8npt and use a plug if not needed for vacuum 

Create your own design on the plenum to fit your needs. Some like to do a box style, some like the pipe style. Plenum plate is rounded at a 4” diameter on a 3.5” wide plate. This lets you use from 3.5” or 4” elbows with minimal work. (4” for larger planum volume).
