AEM Universal EMS BOSCH LSU 4.2 Wideband 02 UEGO installation Kit

AEM Bosch LSU 4.2 Wideband UEGO sensor is accompanied by installation hardware including a weld-on bung, connector, wire seals, and pins. This sensor is designed for use in exhaust gas oxygen (UEGO) systems, which provide a wider air-fuel ratio (AFR) measurement range compared to traditional narrowband oxygen sensors.  Unlike narrowband sensors that only indicate a rich or lean condition, wideband sensors can measure the exact AFR, which is essential for tuning performance engines and ensuring proper emissions output.Warranty
