The AEM X-Series Digital Boost Display Gauge (30-0308) is a must-have for high-performance enthusiasts. Packed with impressive features, this gauge delivers exceptional readability and incredible good looks. The bright center LED display is 87% larger than AEM's previous digital gauges, making it easier to read at a glance. A sweeping green LED "needle" lines the gauge face, providing quick visual reference. Plus, the overall display area is 33% bigger, further enhancing visibility. Despite the enlarged display, the X-Series Gauge maintains a compact 2-1/16" (52mm) housing that can be mounted practically anywhere. Its advanced single-board design keeps the depth under 0.825", with a cup depth of just 0.200" - allowing for versatile installation. Offering highly accurate boost pressure readings up to 60 PSI or 4 BAR, this digital gauge combines unmatched performance with a sleek, modern aesthetic. It's the perfect addition to any high-performance vehicle. X-Series Digital Gauges include new technological features that make them easier to use. Two buttons on the faceplate deliver programmability for peak/recall, standard or metric center LED readout and sweeping LED needle, and user-selectable threshold warnings. The gauges are AEMnet CAN-bus enabled, so they can be daisy chained together for use with the Infinity ECU, Series 2 EMS, AQ-1 Data Logger, or 3rd party EMS or logger that accepts AEMnet. 0-5V analog outputs are also included for inputting into data loggers and engine management systems.
