BBK's front oxygen extension harness kit is a required add-on when installing BBK 1986-2010 Mustang GT specific Long Tube Headers to ensure your engine operates at a safe air/fuel ratio. The 18" leads are a direct fit between your sensors and the factory wiring harness with no cutting, splicing or tapping required. However, some directional tabs may have to removed with a razor knife or smooth tooth file for proper engagement.
Note: Oxygen sensors are not included in contents of this kit.
