AiM 14mm CHT Sensor
Install this Coolant Head Temperature Thermocouple between the head and spark plug (under the spark plug hex) to monitor temperatures ranging from 0 to 572° F (up to 300° C). Fits 14mm spark plugs (including Yamaha KT100). 0.07" thick sensing ring.
This thermocouple is equipped with a K-Type (2-blade flat) connector. Some AiM MyChron4 2T and MyChron5 2T karting dashes and a few MyChron3 and MXL auto dashes have the matching connector in their sensor harness. These dashes can use the MyChron K-Type Thermocouple Patch Cable (Part No. MC-203-01) to extend the reach if needed.
