I need thread size for EGT's.

[Billdogg]

I bought a used THDP this winter that had a bung welded in for an EGT or WB02. I dont' have either of those yet, and want to get the car running, so I need to plug it up.

Is there a common thread size for these, and if so, what is it? Thanks in advance.

Normally 1/8 NPT

If the bung is for a wide band I think it's likely threaded M18 1.5

a WB O2 bung would be much larger than an egt bung.
