I can't remember off the top of my head, but I remember one time, I had to re-thread an o2 port at work. I used a spark plug rethreader, and it worked perfectly. 14mm x 1.25 is the size, I THINK

it may be 18mm I did it a long time ago. either way it's either 14 or 18mm x 1.25

was skeptical on anything below 18mm..

anythin below seemed somewhat on the small side..

so the purchase was made on 18mm and 20mm with both 1.25 and 1.5 just in case...

18mm 1.5 was the winner..

thanks for the help fellas...

why would you plug it? Don't u need the O2 sensor for an air/fuel meter or to at least keep the ECU informed of the air/fuel ratio?



I'm definitely missing something
