Product Description
Michigan Motorsports 12" & 24" 4-Pin LS O2 Sensor Extension Set
Black Square 4-Pin Oxygen Sensor Extensions | Includes 12" & 24" Cables | Fiberglass Heat-Resistant Sleeving
Extend the reach of compatible GM LS oxygen sensor wiring with this 12" and 24" 4-pin O2 sensor extension set. Designed for applications using the black square 4-pin oxygen sensor connector, this package includes two premium extension cables to simplify header, H-pipe, and custom exhaust installations. The fiberglass heat-resistant sleeve helps protect the wiring from heat generated by aftermarket exhaust components, while factory-style Delphi/Packard connectors, terminals, and seals help provide a clean plug-in installation without cutting or splicing the original harness.
Key Features & Benefits
- Two O2 Sensor Extension Lengths Included: Includes one 12" extension and one 24" extension to provide added routing flexibility for compatible front or rear oxygen sensor wiring needs.
- Black Square 4-Pin Connector Design: Built for compatible black square 4-pin oxygen sensor connections. This connector style is different from the gray square 4-pin connector used on some applications.
- Fiberglass Heat-Resistant Sleeve: Each extension features protective fiberglass sleeving to help shield the wiring from heat generated by aftermarket headers, H-pipes, and nearby exhaust components.
- Factory-Style Connector Components: Uses Delphi/Packard-style connectors, terminals, and seals consistent with OEM GM wiring harness construction for a clean plug-in extension solution.
- No Factory Harness Cutting Required: Eliminates the need to cut and splice the original oxygen sensor wiring, helping simplify installation and future header or exhaust service.

Notes
- Black Plug Verification: These extensions use the black square 4-pin connector. Confirm that both your vehicle harness and oxygen sensor use the matching black plug before purchase.
- Gray Plug Exclusion: Do not use these extensions for applications equipped with the gray square 4-pin oxygen sensor connector.
- Header Installation Use: Aftermarket headers and H-pipes can relocate oxygen sensor bungs farther rearward, making an extension harness necessary to reach the factory wiring connection.
- Installation Note: Route the extensions away from direct exhaust contact, sharp edges, moving components, and areas where the wiring could become stretched or pinched.
