AEM’s Digital Oil Temperature Gauge unites unsurpassed accuracy, speed and control with an easy to read, digital LED interface. AEM digital gauges also offer a 0-5v analog output for use with data loggers and virtually any engine management system, such as the AEM EMS or FIC.

The AEM Oil Temperature Gauge has a bright LED display that shows oil temperature in 1 degree increments, and a sweeping LED "needle" that lines the edge as oil temperature changes from 100 to 300F. Knowing your oil temperature is critical, as your engine's oil breaks down at high temperatures. Compounding this is the fact that coolant temperature does not reflect oil temperature - so even in spirited street drivng you may be breaking down your oil! Now you'll be able to see and log to the exact degree how hot your oil is. Each gauge includes interchangable silver and black bezels and black and white faceplates to personalize the look of your gauge - it's like having 4 gauges in 1!
