The AEM Bosch LSU 4.9 wideband UEGO replacement sensor is a factory-calibrated sensor intended to replace the mounted wideband probe used with compatible AEM controllers. It includes the attached cable and male connector with a laser-etched, calibrated resistor matched to that sensor. Lab-calibrated to 0.1 AFR accuracy, it does not require free-air calibration when used with an AEM wideband controller.
