2018-2020 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 2018-2020 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, 6-pin connectors to ensure a perfect fit. These Mustang O2 extensions control the upstream oxygen sensors.
Some connectors may require the small directional location tabs to be removed from the ends of the connectors to click into place.
