AEM X-Series Water Temperature Gauge Kit 52mm 40-150°C / 100-300°F | 30-0302

The AEM 30-0302 water temperature gauge from the X-Series is a digital 52 mm gauge that accurately displays your coolant temperature, built for performance and motorsport use. With a mounting depth of just 21 mm, it fits in virtually any dashboard, gauge pod or race interior.

The central digital display is up to 87% larger than on the previous generation, so you can read the temperature even at a quick glance. Around the display sit 24 green LEDs that show at a glance whether the engine is still running in the safe range, ideal during a drift run or on track.

The gauge has a dual scale: you choose between 40 to 150°C or 100 to 300°F. The two buttons on the front let you set the peak/recall function, warning values and the LED sweep. A built-in sensor dims the display automatically, so it is perfectly readable by day and by night.

Fitting and delivery

Screw the 1/8″ NPT sensor into a coolant passage or into an adapter in the radiator hose, connect the gauge to positive, earth and ignition, and mount it in a 52 mm hole or gauge pod. Allow one to two hours of work. The kit is in stock and is shipped immediately.

An AEM water temperature gauge with a large digital display and 24 LEDs that tells you at a glance whether your engine is still cool enough.

Why choose this AEM water temperature gauge?

With a standard gauge, you often notice an overheating engine too late. The AEM X-Series shows the exact temperature, warns you with an adjustable limit and logs the peak of your session. Thanks to the CAN bus and analogue output, it grows with your build if you later fit an aftermarket ECU or data logger.

Frequently asked questions

Is the temperature sensor included in the kit?

Yes, the kit is complete with a 1/8″ NPT water temperature sensor, wiring, bracket and mounting hardware.

Can I connect the gauge to an ECU or data logger?

Yes, via the 0-5V analogue output or via AEMnet CAN bus, for example to an AEM Infinity ECU or AQ-1 data logger.

Can I set a warning?

Yes, you set a warning value yourself using the buttons on the front. The gauge also remembers the highest temperature measured (peak/recall).

Does the gauge fit a standard gauge pod?

Yes, it has the standard diameter of 52 mm and, with a mounting depth of 21 mm, is exceptionally compact.
