Installation Notes and Tips

Installation requires removing the old oxygen sensor and threading the Bosch 17015 sensor into the exhaust manifold or pipe using a 22 mm oxygen sensor socket. Ensure the wiring harness is routed properly to avoid contact with hot or moving parts. The 5-wire connector should be securely attached to the vehicle’s harness, matching the male rectangular connector. No mounting bracket is included, as the sensor mounts directly via threading. It is recommended to use anti-seize compound on the threads to facilitate future removal.
