Product Description
Michigan Motorsports 24" O2 Oxygen Sensor Extension Harness
Plug-and-Play O2 Sensor Extension for GM LS & LT Engines
The Michigan Motorsports 24-inch Oxygen Sensor Extension Harness is designed to simplify O2 sensor relocation when installing aftermarket headers on GM LS and LT-based engines. Many long-tube and performance headers move the O2 sensor bungs farther downstream, making the factory wiring too short. This extension harness eliminates the need to cut or splice factory wiring, preserving signal integrity while making header installation and removal significantly easier. Featuring the correct black square 4-pin connector, this harness ensures accurate sensor readings and a clean, reliable installation.
Key Features
- 24" Extension Length: Provides the additional reach needed when O2 sensor locations are moved rearward by aftermarket headers.
- Plug-and-Play Installation: Connects directly to the factory harness with no cutting or splicing required.
- Correct Black Square 4-Pin Connector: Uses the black square-style connector, which is different from the gray square 4-pin plug.
- Maintains Accurate O2 Readings: Prevents signal issues commonly caused by cutting and splicing factory wiring.
- Ideal for Long-Tube Headers: A must-have accessory for hassle-free header installations and easier future service.
Key Fitments
- LT1 Applications: Fits 1993–1997 Camaro and Firebird equipped with LT1 engines.
- LS Applications: Fits 1997–2004 LS1 and LS6 engines.
- Later LS Engines: Compatible with 2005–2008 LS2, LS3, and LS7 applications using the black square 4-pin O2 connector.
