The AEM X-Series Wideband UEGO Air/Fuel Ratio Sensor Controller Gauges set a new standard in precision and speed, utilizing innovative X-Digital technology. Renowned for their rapid response, these gauges outperform competitors in independent tests, ensuring you get the most accurate air/fuel ratio readings for your vehicle.

Advanced Display and Design: The X-Series Wideband UEGO AFR Gauge features a striking faceplate and a new seven-segment center display that is 87% larger than AEM's previous models. This larger appearance is coupled with a common 52mm size for effortless mounting. Its slim profile, with an ultra-thin gauge cup depth, opens up a vast array of mounting possibilities.
