They typically use Alcor 86253 Type K thermocouple probes. They are Garmin P/N 494-70000-00, or can be bought from Aircraft Spruce.

There seems to be a bayonet and a srew in version with the same type number.
Which should it be ?

The 86253 is a bayonet, which is a "screw-in" version. The other type uses a ring terminal that goes under a spark plug referred to as "gasket" type. There's more information about these on Alcor's website with all of their documentation.
