Default CHT spark plug ring size?

Just a quick question....(and yes, I searched ).

I am adding a 6-cylinder cylinder head temperature (CHT) gauge.

What is the size for the ring sensors that fit under the spark plugs? I think I read on Pelican it is 14 mm but want to confirm before ordering.

Thanks.

Adding a bunch of sensors myself in the next couple weeks...

How many CHT sensors?

14mm is perfect.

I am adding one of these but with longer sensor wires (standard is 8' and not long enough).

I was about to suggest going with a gauge/sensors developed for the aviation industry...
FWIW... I did some reading on egt and cht sensors over the weekend and many pilots seem to favor the KS Avionics sensors.
How many sensors, all 6?

I have 3 friends with small planes and they all suggested this type but I am sure they are all good.

Yes, I am going with 6 sensors as I have read that CHT is more sensitive and quicker to react to unfavourable conditions than oil temp or EGT (that is why I just put in one EGT sensor per bank).
