AEM 30-0302 X-Series Temperature Gauge

Because “it feels a little hot” isn’t exactly data.

The AEM 30-0302 X-Series Temperature Gauge is a high-precision digital gauge designed to give you accurate, real-time temperature readings without the lag and guesswork of old-school analog setups. Whether you’re monitoring coolant, oil, transmission, or basically anything that gets hot and expensive, this gauge keeps you informed before things go sideways. AEM’s X-Series lineup is known for its fast response times and insanely bright display, and this one doesn’t disappoint. The center LED readout gives you quick, easy-to-read numbers, while the color-changing outer ring can be configured to visually warn you when temps start creeping into “uh-oh” territory.
