AEM Air Temp Sensor Kit – 3/8" NPT with Connector & Pins

The AEM Air Intake Temperature (AIT) Sensor Kit is designed to accurately monitor incoming air temperatures on the inlet side of the engine—an essential parameter for ECU tuning, air-fuel corrections, and advanced data logging. Ideal for forced induction and naturally aspirated engines alike, this compact sensor delivers fast, reliable temperature data across a wide operating range.

Built for Precision and Reliability
Manufactured with a robust brass sensor body and rated to operate from -40°C to 135°C (-40°F to 275°F), this AEM sensor features a fast thermal time constant and excellent accuracy (<1.5°C). It includes a 3/8” NPT aluminium weld-in bung, weatherproof connector, pins, and seals for complete, hassle-free installation.
