i got a 4-wire honda oxygen sensor and i like to know what size bung will i need. i went to a shop to look for it and the 3/8 that they have doesn't work. any idea what size is it?

lastly, the color of the wires of the honda o2 sensor is 2 whites, black and gray. the 2 whites are for the heating element which wire is the signal, black or gray?

any help will be appreciated.

 

I think that most o2 sensors are the same size thread pitch...but, I could be wrong. In any case, a well stocked muffler shop should have what you need, or you could bring it to a hardware store and find a nut to have them weld on nut=bung.

Also, what brand o2 sensor did you buy? If it was ntk/ngk or denso it should have instructions for the wiring...

the o2 sensor i got is an original honda oxygen sensor and i'm not sure if it's ntk/ngk or denso. the shop who sold it to me said it's from a B16 EF so that means it's a honda OEM o2 sensor.
