Product Overview
AEM X-Series Temperature Gauge 30-0302 (100-300F / 40-150C)
The AEM X-Series temperature gauge gives you a precise digital reading with the at-a-glance feel of an analogue dial. A large central LED shows the exact figure while 24 green LEDs around the edge sweep like a needle. With a range of 100–300°F (40–150°C) it suits coolant, engine oil or transmission temperature, and it fits a standard 52 mm (2-1/16″) gauge pod.
Features
- Centre LED display 87% larger than AEM’s earlier digital gauges
- Outer ring of 24 LEDs acting as a sweeping needle
- Peak recall, °F/°C selection and warning thresholds via two face buttons
- Auto-dimming to suit day and night driving
- Slim build: under 0.825″ overall depth and 0.200″ cup depth
- Positive-locking connectors
Outputs and data logging
The gauge outputs its reading over AEMnet CAN-bus and a 0–5 V analogue channel, so it can be daisy-chained with an AEM Infinity ECU, Series 2 EMS, AQ-1 logger or a compatible third-party logger, or used to feed a dash without fitting a second sender.
What’s included
The kit comes with the gauge, a temperature sensor, wiring harness, black bezel and double-sided black water temperature faceplate (Fahrenheit on one side, Celsius on the other). AEM’s 30-0302-ACC accessory kit, sold separately, adds a silver bezel, white faceplates and black oil and transmission faceplates if you want to use it for another fluid.
Fitting advice
Mount the sensor where it is fully immersed in the fluid being measured, such as a thermostat housing port, coolant hose adaptor or oil sandwich plate. Check the sensor thread against your port before starting, as an adaptor may be needed. Power the gauge from an ignition-switched supply and set your warning threshold once fitted.
