The AEM Digital Oil Fuel Water Temperature Gauge combines unsurpassed accuracy, speed and control with an easy-to-read digital LED interface that displays oil temperature in 1 degree increments, and a sweeping LED "needle" that lines the edge and moves as oil temp changes from 0 to 100. The aftermarket digital oil temp gauge's readout will automatically increase and decrease in intensity due to the built in ambient light sensing photocell. AEM's digital oil temp gauge includes a 0-5v analog output for use with data loggers and virtually any engine management system, such as the Infinity ECU, Series 2 EMS or AQ-1 Data Logger, making it the perfect solution for users who need to monitor and data log oil temps at high RPM on tuned engines. Each AEM oil temperature gauge includes interchangeable silver and black bezels and black and white faceplates to personalize the look of your gauge.
