AEM 30-0302 X-Series Digital Temperature Gauge Water/Trans/Oil 100-300F

Vehicle Fitment

• Universal Fit - compatible with any 12V vehicle with a standard 2-1/16" (52mm) gauge pod opening

Fitment Notes

• Universal fitment - not vehicle-specific. Customer must verify gauge pod clearance and sensor thread compatibility prior to installation.
• Comes assembled with a black bezel and black water temperature faceplate only. Silver bezel and additional faceplates (white water temp, black/white transmission and oil temp) require separate purchase of accessory kit 30-0302-ACC.
• Sensor installation location (water, oil, or transmission) must be confirmed by the installer. Use appropriate thread adapter if needed.
• AEMnet daisy-chain compatibility requires AEM Infinity ECU, Series 2 EMS, AQ-1/AQ-2 Data Logger, or compatible third-party EMS.
• Use a 5A inline fuse on the switched 12V power supply line during installation.

Product Description

The AEM 30-0302 X-Series Digital Temperature Gauge is a high-precision, multi-function instrument designed to monitor water, transmission, or oil temperature in any performance or racing application. Its bold 4-digit center LED readout - 87% larger than AEM's previous generation - combined with a 24-LED sweeping outer ring delivers at-a-glance readability under any lighting condition, enhanced further by an integrated auto-dimming sensor.

Built for modern performance builds, the 30-0302 features AEMnet CAN-bus connectivity for daisy-chaining with AEM's Infinity ECU, AQ-1/AQ-2 Data Loggers, or compatible third-party engine management systems, as well as a 0-5V analog output for broader data logging integration. Its ultra-slim 0.825" depth fits nearly any gauge pod or custom dash location, and its programmable peak recall and threshold warning alerts give drivers critical engine data without distraction. The gauge ships with a black bezel and black water temperature faceplate; the optional 30-0302-ACC accessory kit adds silver bezel and additional faceplate options for oil and transmission temperature monitoring.
