AEM 30-4110 UEGO Air/Fuel Ratio Gauge with Sensor

The AEM 30-4110 Wideband O2 air/fuel ratio UEGO gauge boasts a digital LED display with a sweeping LED ‘needle’ that changes colour based on the air/fuel ratio (AFR) variations. The unit fits conveniently in any standard 52mm (2-1/16″) gauge housing, making it adaptable for most applications, including remote mounting. A crucial component for maximising engine performance, this gauge provides a 0-5V analog output, compatible with data logging and various engine management systems. Each unit includes both black and silver bezels along with black and white faceplates for personalised styling, ensuring a seamless fit with your vehicle’s interior. The Bosch 4.9 LSU sensor significantly enhances speed and accuracy, providing reliable AFR monitoring without requiring free-air calibration. It is important to note that this sensor uses a distinct connector and is incompatible with previous 4.2 LSU sensors used in other AEM products. This AEM gauge is essential for optimising engine tuning to prevent performance loss from over-rich conditions or serious damage from lean conditions.
