O2 Sensor Thread Size?

[Devvon]

I am replacing my O2 sensors and one is stripped. Does anyone know what size thread chaser (cleaner) to use?

If ya Google it, it looks like everyone is saying M18 X 1.5.
Just take a new one or a good old one to any hardware or auto parts store and use that thread pitch thing.

Yep, it is M18 x 1.5. Autozone has a thread cleaner for $9.99. It took a bit of time to clean out the threads but it worked...:yesy:
