o2 sensor

Is it ok to use anti seize compound on the threads on an o2 sensor .

If memory serves, it's officially not okay, but the last one I put in had copper antiseize pre-installed on its threads.

I believe it's all about the possibility of contamination of the sensor by the metals in the antiseize. If you use very little and put it on the threads in such a way that none goes forward into the exhaust system, you'll be fine.

I've always put copper antiseize on mine – you'd never be able to get the darned things out otherwise.

I can't recall if i have ever even seen one that came out of the box without antiseize on it.

Yeah, I can't remember all of them, but I specifically remember the one I did two weeks ago, so that's all I could swear by.

Yes use anti seize.

And any silicone you use absolutely must be O2 sensor safe or it will kill the sensor in short order.
