The BBK O2 Wire Harness Extenders are designed to simplify the installation of full-length headers on your 2005-2018 Dodge or Chrysler V8. These extensions are essential because the O2 sensor locations are relocated on full-length headers, eliminating the need to cut into your factory wire harness.

Just transfer your factory oxygen sensors to the new location in the collectors and click the extensions into place on the OEM harness. Some connectors may require the removal of small directional location tabs from the ends to ensure a secure fit.\n\nThe BBK Rear O2 Sensor Extensions are specifically designed for 2005-2017 Dodge 6.1L/6.2L/6.4L vehicles with 4 pin square style connectors. Each pair of extensions measures 24 inches in length, providing the perfect solution for ensuring a factory-like installation without the hassle.
