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.

Features & Benefits:

  • Prevents CEL
  • Maintains OBD2 catalyst monitoring function
  • Plug and play install
  • GT & V6 compatible

O2 extension
The indexing tabs did not align with the factory harness. A little trimming and they fit fine.
