The X-Series AEM OBD2 Gauge (PN 30-0311) has a bright four-digit LED display that is 87% larger than our original digital gauges and provides better readability. A sweeping LED “needle” lines the edge of the gauge face for quick reference. A 33% overall increase in the gauge face display makes it easier to see at a glance. X-Series Gauges come with a black bezel and faceplate, and an optional silver bezel/white faceplate accessory kit is available (PN 30-0311-ACC, sold separately).

NOTE: The 30-0308 comes with a black bezel and reversible black PSI/BAR boost pressure faceplate. You will need to purchase the optional 30-0308-ACC accessory kit to get the silver bezel and reversible white standard/metric boost pressure faceplate. Each faceplate is double-sided with standard PSI on one side and metric BAR on the other. The calibration for standard or metric display is easily performed using the buttons on the face of the gauge.

NOTE: The 30-0302 comes with a black bezel and black water temperature faceplate. You will need to purchase the optional 30-0302-ACC accessory kit to get the silver bezel, white water, transmission and oil temp faceplates, and black transmission and oil temperature faceplates. Each faceplate is double sided with standard Fahrenheit on one side and Celsius on the other. The calibration for standard or metric display is easily performed using the buttons on the face of the gauge.

Despite the larger display, X-Series Gauges are contained in a standard 2-1/16th-inch (52mm) diameter housing for mounting in a standard gauge pod. Thanks to an advanced single board design, X-Series Gauges have an incredibly slim overall depth of under 0.825″, with a cup depth of only 0.200.” This shallow cup depth allows X-Series Digital Gauges to be mounted practically anywhere.
