BBK 12 inch O2 Sensor Extension for GM features wire harness extenders which are a must when installing full-length headers. The factory connectors allow for the simple installation of O2 sensors due to the fact that the locations are moved on full length headers. The factory OEM connectors and heat protective sleeves make installation a snap. The connectors may require the small directional tabs to be removed on the ends of the connectors to fit some applications.
