I'm going to be putting in my new X-pipe sometime during the weekend. But I need to find the thread size for O2 sensors so that I can cap off two of the bungs. I really don't want to spend $10 to buy one online and I don't want to spend $20 to get a K&N one from Auto Zone. I'm sure I cna just grab a bolt from Home Deopt and plug it in there, but I don't know the bolt size and thread size I'll need.

I'm thinking 18mm x 1.5 but I just want to be sure. Or is htis going to be one of those things that's next to imposible to find (like my 1/16 - 27 NPT tap for my nitrous nozzle)

Yup....18mm x 1.5...double checked it with my rethreading bit.

Well Home Depot didn't have anything larger than a 16. I hope I'm not gonna have to special order it[:@]

Get a spark plug chaser. Prolly easier to find than a tap that size.

Just to give you an idea why I need it... I bought an X pipe but it has bungs for 4 sensors. My driver's side is a bosch narrow band and the passenger side is a bosch wideband (with narrowband emulation.) That leaves two useless bungs that I need to cap off for good.
