O2 Oxygen Sensor Extension Wire Harness; Downstream

When installing long tube exhaust headers, the O2 sensors are relocated on the header that is no longer in the factory location and the factory O2 sensor connectors will not reach to connect any longer. These extension harnesses are a must when Installing Full Length Headers. This harness features OEM Factory connectors to allow simple plug-in installation to the factory wire harness so that the relocation is super simple and does not require any splicing of the factory harness at all.
