BBK's rear oxygen extension harness kit is a required add-on when installing BBK Long Tube Headers to maintain the OBD2 catalyst efficiency monitor and prevent throwing a continuous CEL (Check Engine Light). The 12" leads are a direct fit between your sensors and the factory wiring harness with no cutting, splicing or tapping required.
Note: O2 sensors are NOT included in this kit.
