Overview

These are all "K-type" thermocouples and they come in sizes 10mm, 12mm, 14mm and 18mm. The sizes refer to the thread diameter of the spark plug the probes are used on most automotive engines use 14mm plugs, the Jabiru engine and Rotax 912/914 use 12mm plugs. The big Lycomings and Continentals use 18mm plugs. Some motorbike engines use small 10mm plugs.

No problem with this and the other parts received under the same order. However, I was disappointed with the time the time the remaining parts were left on back order. This is probably not Aircraft Spruces fault due to the virus etc etc but had more stock been held it may have been avoided.
