Bosch LSU4.2 Lambda Sensor Connector - Male https://www.efihardware.com/products/2187/Bosch-LSU4.2-Lambda-Sensor-Connector-Male
This connector is the same male connector as the Bosch LSU4.2 Lambda Sensor. Use this connector, plus our connector H-OXYLSU42C to make an oxygen sensor extension cable.
**** Please note this is not a suitable replacement plug for the Factory O2 Sensor harness plug as the original contains a calibration resistor. ****
