GM IAT Sensor with open element, includes 6″ pigtail
GM IAT Sensor with open element is the recommended ‘Fast-Response’ Intake Air Temp Sensor (IAT) for use on forced induction vehicles. GM IAT Sensor with open element are proper GM-style sensors for use with ALL MegaSquirt & MS3Pro ECUs and include a 6″ wire pig-tail with weatherproof connector.
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.
Use the following 3 point curve calibration data when using GM IAT Sensor with open element and your MS system:
| Temperature | Ohms |
| 48 degrees F | 7000 |
| 87 degrees F | 1930 |
| 146 degrees F | 560 |
