Never use any type of chemical on the 02 sensor. That will mess it up. Don't use anything. Just screw it in. Teflon tape would last maybe 10-15 seconds before it burns away.

No they come with anti seize on them allready , just pull yours out and install the new one

 

Pino is right - but they don't come with ENOUGH anti-seize. Teflon would burn away almost immediately, as Stinger said, and that would be good since the sensor must be grounded to the pipe.

Don't worry about sealing the thread with a sealant, since there is a gasket washer installed on the sensor just like gasketed spark plugs. Just apply a little extra anti-seize to the threads only and screw it.

i like the lead based anti seize instead of the silver kind. little harder to find but i think it works better.
