If you are replacing an O2 sensor with a new one, disconnect the electrical plug from the vehicle harness, cut the wires off at the old O2 sensor, slip a 7/8" box wrench over the O2 sensor and remove it by turning it counterclockwise.

Install the new O2 sensor using a 7/8" open end wrench, tighten it as you would a spark plug, reconnect the electrical plug into the vehicle harness, done.
