O2 sensor installation (1 Viewer)

Stupid question, but: When installing, do I use any form-in-place gasket, or just the metal gasket?

just the supplied gasket

are you re-using the existing gasket or installing a new one? If new one, no form-a gasket needed.

Existing O2 sensor, new gasket.

Existing O2 sensor, new gasket.

Then you're good to go as is. Nothing else required.

I'd suggest putting a little dab of copper antiseize on the O2 sensor threads if the new sensors didn't already come with it applied. Using antiseize on the threads will make removal of the sensors later on alot easier. But just a word of caution, make sure the antiseize doesn't get on the tip of the sensor that's sticks into the exhaust stream.
