Hi
There for a CHT sensor for EFI.
1302Steve
thank you steve 
Thats Cylinder Head Temperature Sensor for fuel Injected engines.
Dave are all these heads like these ? these would be late model correct .
Most of the new ones you buy have these installed as there a universal head.
Old origional ones wont have them,
Would it be possible to use for a aftermarket CHT gauge? and would it give a simialr reading as the one under the stud or spark plug?
