Anyone know the thread size on the O2 sensor bungs?

and or the threads ON the 02 sensors themselves? i dont have any laying around to check them.


thanks for any responses.

IDK if you're trying to plug it or not but here's a couple numbers and ways.

Easiest thing to do would be to snap off a spark plug and use that to plug it. It's either a 14mm spark plug thread or something that's close to it and work would be 3/4x16 bolt.

If you're just trying to replace it, you wont need to know that.

well i WAS going to make one and didnt have a sensor to measure the threads. I am getting the UPR catless X for my 04 and am going to relocate the bugs so i dont need to get extensions. I got the MIL's and actually managed to get bungs for free from an exhaust shop.

ill prob use a bolt to plug them and weld it closed.

thanks nerd

I'm here to serve. IDK if it matters but here's a way to make your own extentions.

yea i actually came across that at one point. im not a fan of having to splice into my harness and whatnot. i like to keep things stock with the least "hacking" needed.

like i said, ive already got the bungs and its just as easy to plug and reloacte the bungs on the pipe.

thanks again

It's an M18x1.5 thread--18mm diameter x 1.5mm pitch...
