2018-2023 Mustang O2 Extensions

When doing a long tube header installation on any Mustang, chances are you'll need to extend the oxygen sensor harnesses. BBK takes out the guesswork with this 2018-2023 Mustang GT O2 extension kit! The factory harness cannot reach the new O2 sensor location, therefore these extension harnesses are needed. BBK utilizes factory-style, 5-pin connectors to ensure a perfect fit. These Mustang O2 extensions control the upstream oxygen sensors.

Installation Note

  • Some connectors may require the small directional location tabs to be removed from the ends of the connectors to click into place.
