I wouldn't worry about it. Any leakage would be minor.
However, if you are worried about it you can put some high temp
sealer around it.
Don't know if a hose would work in this situation or not due to engine noise.
Get lenght of small hose, stick one end in ear, and use the other end
to listen for leaks.

Thanks for that advice on the high temp sealer.
Someone said that the threads are the ground for the electrical connection.

I did not explain well enough before.
Sealer around the sensor did not mean on the threads nor coating the sensor.
Picture a thin rubber band's worth where the sensor and manifold meet.
