AEM Digital Oil Pressure Gauges combine unsurpassed accuracy, speed and control with an easy-to-read digital LED interface that displays oil pressure in 1 PSI increments, and a sweeping LED "needle" that lines the edge and moves as oil pressure changes from 0 to 100. The oil pressure gauge's digital readout will automatically increase and decrease in intensity due to the built in ambient light sensing photocell. AEM's digital oil pressure gauges include 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 them the perfect solution for users who need to monitor and data log oil pressure at high RPM on tuned engines. Each gauge includes interchangeable silver and black bezels and black and white faceplates to personalize the look of your gauge. Features:
