The Kooks 12-inch Oxygen Sensor Extension Harness is designed for Ford Mustang applications to provide proper oxygen sensor reach when installing performance headers. This extension harness features a 4-pin round connector that allows factory O2 sensor wiring to connect correctly when header installations reposition the sensor location. Built to maintain accurate communication with the engine management system, this harness helps ensure reliable sensor operation and engine performance. While typically included with compatible Kooks header kits, this part is intended as a replacement for damaged or missing oxygen sensor extensions. For certain header installations on 2005-2010 Mustang GT automatic models, two extension harnesses may be required.
