o2 sensor redtop plug?

[bmxer882x]

Alright so i got my sr running after my swap and have been driving it everything is going well except, in my rush of excitement i forgot i never tightened the o2 plug that came with the test pipe. It is for a skinny type o2. The testpipe i got was a godspeed but that shouldnt have anything to do with it.

What i need to know is what is the thread pitch for the o2 sensor spot? I have read m12x1.5 but having gone to the store and bought a m12x1.25, 1.5, and 1.75 and none of them working im thinking its a pipe thread, anybody know the exact size before i go buying more plugs?

Thanks alot!

The skinny o2 sensor thread pitch is M12x1.5 but the Godspeed crap probably has a different size all together. Best bet is to take the pipe to a hardware store and find something that fits.

alright thanks, i may just retap it to be what i have. basically i just want it plugged off. Of course the only godspeed part on my car gives me trouble...
