When doing a long tube header installation on the 2015-2017 Mustang GT you'll need to extend the oxygen sensor harnesses. Michigan Motorsports takes out the guesswork with this 2015-2017 Mustang GT O2 extension kit! The factory harness cannot reach the new O2 sensor location, therefore these plug and play extension harnesses are needed. We utilize factory style connectors to ensure a perfect fit. These Mustang O2 extensions extend the upstream oxygen sensors.
Premium Sensor Extensions are wrapped in a Fiberglass Heat shield
