Cobb DP O2 bung plug size?

If its a standard size o2 thread, it's the same as a spark plug. Don't quote me but I believe it's 14mm x 1.25.

 

Go to the parts store, find a universal replacement oil drain plug that fits. I did that with my EGT bung.

 

EGT plug is 12 x 1.5, not sure if thats the same as the O2 bung though.

Anyone know the size of it... i need something to plug it up with.. i never got it in the box idk why...

 

It doesnt come with a plug. Its predrilled for your factory EGT sensor. You can have the blank bung drilled for an aftermarket EGT bung, but you will need to find a machine shop to do it for you.

 

and yes the one predrilled by Cobb is 12x1.25, same as our lug bolts

What's 0.25 mm between friends :confused:

 

It would just be a tight fit :lol:

Like throwin' a hotdog down a hallway... oh wait, talking about something completely different.:lol:

 

1.25 vs 1.5 thread pitch is enough differnce to matter.

ignore him, he'll go away.
