AEM's 30-0305 X-Series 0-1800F/0-1000C Digital Exhaust Gas Temperature (EGT) gauge combines incredible looks, increased readability and a multitude of new, easy-to-use features! It is a must for users who want a highly accurate EGT readout in their high performance vehicle. Visual improvements include a bright center LED display that is 87% larger than our original digital gauges and provides better readability. A sweeping green 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.
