SVE Oxygen Sensor Extensions

Complete the long tube header installation on your 1987-2010 Mustang with this O2 extension harness kit from Special Vehicle Equipment®! This SVE oxygen sensor extension harness sets feature a direct plug-in design to prevent the cutting and lengthening of your oxygen sensor wires, thanks to the factory connections. These SVE O2 sensor extensions utilize heat-protective sleeves to protect the wire insulation from damage by the headers. The factory harness cannot reach the new O2 sensor location when installing longtube headers; therefore, these extension harnesses have been designed 12" in length to ensure proper use of your upstream O2 sensors. Ensure the O2 sensors are properly connected to the factory harness of your 1987-2010 Mustang using these SVE O2 extensions!
