Plug-and-Play System. When modifying your Mustang exhaust system, you may realize that the stock O2 sensor harnesses may be short and cannot connect perfectly with your O2 sensors. This is why you need the Kooks O2 Sensor Extension Harness that will enable you to bridge this gap and have your Ford Mustang vehicle up and running.

Quality Construction. Crafting of the Kooks O2 Sensor Extension Harnesses starts with heavy-duty, aircraft-quality stainless steel. This superior-quality material produces long-lasting and corrosion-resistant extension harnesses that will serve you for several years. The harnesses will perfectly fit into your stock oxygen sensors without any difficulty.

A Perfect Upgrade. The Kooks O2 Sensor Extension Harness is a perfect replacement for your stock wiring harness. It can help you upgrade your exhaust system as it will connect your stock O2 sensors with a new mid-pipe or headers. This way, you won't have old wires dangling around and your vehicle will pass any inspections.

Warranty. Kooks Headers and Exhaust® believe that their O2 Sensor Extension Harness is free from any manufacturing defects or structural and material faults. Therefore, they provide a limited manufacturer’s warranty for their extension harnesses giving you the peace of mind that you need.

Application. The Kooks O2 Sensor Extension Harness perfectly fits into all 1996-2004 Ford Mustang V8 models without the need for any modifications. Sold individually.
