Seeking clarification, 02 thread pitch
Is it M18 x 1.5?

I am ordering the parts for my custom exhaust and I haven't gotten a straight answer on the O2 thread for the bung. I don't want to pull an 02 or get one ordered in just to find the thread pitch, hope you guys can help.

Thanks in advance,
Matt

M18x1.5 is the correct bolt size.
