How Should Special Care Be Taken When Servicing an Oxygen Sensor on Subaru Impreza?

For turbo models, disconnect the battery, detach the sensor harness clips, loosen the wheel lug nuts, remove the wheel, unscrew the sensor, and apply an anti-seize to the sensor threads. For the downstream sensor, disconnect the sensor, apply an anti-seize compound to the sensor threads, and reverse the procedure for installation.
