2 lambda sensor questions for Akra carbon install

[thunderlax 0]

In video 1, the installer greases the threads on the actual lambda sensor. In video 2, the installer greases the lambda sensor bolt that screws into the exhaust rather than the actual plug threads. Which is the correct location to apply the black labeled grease? Secondly I would just like to verify that only the hollowed bolt is torqued to the recommended weight while the actual sensor that finally screws into the assembly is tightened snuggly without a recommended torque weight? Thank you for your help, I look forward to my time spent on this forum.

I would grease them both but only use gentle on the sensor, it must not be too much that it could clog the sensor

Yes, use a small amount on any of the threads.

I would think that grease wouldn't survive the heat. I've always used anti-seize; just don't glop it on.

I'd definitely go with anti-seize over any type of grease. For those sensors, it's probably best to go with a nickel based anti-seize that isn't conductive and won't interfere with the signal or ruin the sensor (so long as you're careful to keep it on the threads only).

I think the "grease" is an anti-seize provided by Akra.

I suggest a high temp anti-seize. I prefer copper based.
