Many thanks,

I followed the URL but no P12 there.

Is this the only option?

The real P12.

CPS Substitute

Lockwood Substitute.

One more question: Is it really necessary to put something?
I mean, temperature is not so high...

What is your idea of "not so high"?  

I'll leave it for others to discuss the technical reasons why the manufacturer requires this stuff, but since it actually costs very little, in the grand scheme of things, and it takes almost no time to apply, why would anyone want to avoid using it??

The thermal paste does two things.

It is silicone based. It lubes the threads to help prevent galling and it  transfers heat  to help stave off things like detonation. Roughly 40F.

Anti seize which you shouldn't use on our engine plugs is just old school and it's main property is for galling protection and corrosion. Nothing else. I have some certifed guys at my airfiled that have switched from anti seize to our thermal paste. Sometimes you have to leave old school traditions behind and move forward into the 21st century.

I have been using thermal paste for over 100 hours of operation with a 914 and I change the oil and filter with spark plugs every 25 hours. Does not blunt and smoothly removes
