AEM Bosch 4.9 LSU wideband UEGO replacement O2 sensor - the sensor only (with attached cable and male connector) for replacing a mounted wideband sensor on AEM wideband air/fuel UEGO controllers. A laser-etched calibrated resistor in the connector body is matched to this exact sensor (do not modify), and the sensor is laboratory-calibrated at Bosch to 0.1 AFR, so it never needs free-air calibration with an AEM controller. Sealed housing with 360-degree welded wetted area resists automotive fluids. Connector and pins included.
