Bosch LSU 4.9 Wide Band 5 Wire Air Fuel AFR Sensor is intended to replace an existing mounted wideband sensor used on AEM Digital Wideband UEGO Air/Fuel Controller Part Number 30-4110, 30-0300, & 30-0310. These sensors have a laser etched & calibrated resistor in the connector body. This resistor is specifically created for the exact sensor that it is attached to. Modifying this will invalidate the sensor’s output. The wideband sensor is laboratory calibrated at the Bosch factory. Accurate to 0.1 AFR & does not require free air calibration when used with an AEM wideband AFR controller. Featured & Benefits: .
