AEM 52mm Temperature (Transmission / Oil / Water) Digital Gauge

AEM 52mm Digital Temperature Gauge | Oil, Trans & Water Monitor

Monitor engine fluid temperatures with precision using the AEM 52mm Digital Temperature Gauge. Features a bright LED readout, peak recall, and custom warnings.

The AEM 52mm Digital Temperature Gauge (available in Classic and X-Series models) delivers high-accuracy monitoring for critical fluid systems, including engine coolant, transmission fluid, and engine oil. Built around a standard 2-1/16” (52mm) housing, this compact instrument fits seamlessly into standard aftermarket gauge pods and custom dash panels.

Featuring a bright center numerical LED display alongside a 24-segment sweeping LED outer ring, this gauge gives drivers instant visual feedback on real-time temperature fluctuations. Equipped with built-in 0-5V analog and AEMnet CAN-bus outputs, it allows direct data logging to aftermarket ECUs and stand-alone loggers. Its ultra-slim depth profile ensures easy installation in tight spaces.
