Michigan Motorsports 24" Oxygen Sensor Extension Harness for GM Gen V LT1/LT4/LT5 – Camaro, Corvette, Silverado, Sierra

Upgrade your GM Gen V LT1/LT4/LT5 powered ride with the Michigan Motorsports 24" Oxygen Sensor Extension Harness. This extension enables downstream O2 sensor relocation for flexible routing in tight engine bays, helping you maintain clean wiring and reliable sensor connections. The plug-and-play design means you can install it without cutting or splicing wires, protecting your vehicle’s original wiring integrity.

Built to endure the heat and vibrations of the engine bay, this harness uses rugged materials that stand up to daily driving as well as more demanding setups. Its length provides practical flexibility when placing sensors in areas that are easier to access or cooler, preventing routing conflicts with aftermarket headers and exhaust components. The result is a cleaner installation that supports maintaining accurate sensor data without forcing compromises in your exhaust routing.

Key benefits

• Extended reach that allows safer, neater sensor placement away from heat sources and tight spots.
• Plug-and-play connectors for a straightforward install, preserving the wiring system without splicing.
• Rugged construction designed to resist engine heat and continuous vibrations for long-term reliability.
• Wide GM Gen V compatibility, including Camaro, Corvette, Silverado, and Sierra models with LT1, LT4, or LT5 engines.
• Secure OEM-style connections to help maintain sensor accuracy and consistent engine performance.

What you can expect in everyday use

Think about quick engine bay upgrades or retrofit projects where original sensor wiring falls short. The harness helps you reposition the downstream sensor to optimize clearance, improve aesthetics, and simplify service checks. It also adds a useful margin for future upgrades, such as headers or aftermarket exhaust components, without forcing a rewrite of the wiring harness.

• Plug-and-play installation means less downtime and more time on the road or track.
• Durable materials provide confidence during hot engine starts and aggressive driving.
• Non-invasive routing helps preserve factory wiring harness integrity for resale value.

Compatibility and usage

Suitable for GM Gen V vehicles featuring LT1, LT4, or LT5 engines, including popular models like Camaro, Corvette, Silverado, and Sierra. Use cases include relocation of downstream O2 sensors for aftermarket components or optimizing sensor placement for improved serviceability and monitoring.

Quality you can trust, with a design built for real-world driving. The 24" length offers practical flexibility, while OEM-style connectors help keep sensor data consistent across frequent start-ups and varied driving conditions.
