Hello,

I have an evo ix, but I have an evo viii exhaust. I need to cover, close or block the o2 sensor bung on the exhaust and was wondering if you knew where I could get such a bolt or screw to do it.

Also if anyone knows the pitch and the tread size of the rear O2 sensor bung that would be helpful also.

Thanks,
Daimon

M18x1.5 is the bolt size

 

or slide your o2 from your cat back to that one and get a test pipe or high flow cat... works the same

 

just go to autozone, advance, pep boys...

as mentioned m18x1.5mm and most are oil drain plugs, they work fine..

put some antiseize on it

cb

 

got mine from auto zone

 

i looked for it to no avail. i may have to order online for that bolt.
