GM Closed Element CLT/IAT Sensor with Connector

These are the proper GM-style sensors for use with the MegaSquirt line of ECUs and come with the weatherproof connector and crimp pins.  Suitable for use as a coolant temperature or oil temperature sensor, and is occasionally used as an air temperature sensor in certain applications where a fast acting open element sensor may become damaged. The threads are 3/8″ NPT pipe thread – note that isn’t an actual 3/8″ outer diameter, but a pipe thread size based on pipe inner diameter.
