O2 sensor bung size

[Navigator]

I'm having one of those very senior moments wondering if I already posted a thread asking this question or just imagining I did. Can't find it in a forum search so here goes, hopefully again.

I'm still running my T with tbe O2 sensor installed but now I need to remove it after the custom tune was downloaded by Claviger. However, I do not know what the correct size of the plug I need to buy.

So what size is it and does it require a washer? I'm having a da javu moment as I type this so please Mr. Webmaster, delete this this thread if it is a dupe.

I so hate getting old.

Yes Mike you did ask this some weeks ago, but we don't mind

And yes getting old does suck (and I'm only young with many long Summers and a few bitter Winters under my belt)

Darn but I knew it was a dupe. I gauge my senility level by how many tjmes a week I walk out to my shop and forget why I did so.

M18x1.5 at Ace Hardware.. Got it and thanks gents.

We're heading home from Florida on Wednesday and I'll get at some Rocket housekeeping..I think I'll ride out to the coast on Friday
