O2 sensor thread size.

The bung on my xpipe has a couple messed up threads. What is the thread size so I can chase them before putting in my new O2. Thanks.

I'm 99% sure that it's the same as the large spark plugs. You can get one of those double sided spark plug thread chasers from an auto parts store for like $5 and use it.

It is from what I remember.
