The Kooks 24-inch Oxygen Sensor Extension Harness is designed for Ford performance applications to provide additional wiring length when installing aftermarket headers. Featuring a 4-pin round connector, this extension allows the factory oxygen sensor wiring to properly connect when the sensor location changes during header installation. Built for reliable signal transfer and durability in high-temperature engine bay environments, this harness helps maintain accurate oxygen sensor communication with the engine management system. While typically included with compatible Kooks header kits, this extension harness is intended as a replacement for damaged or missing oxygen sensor extensions.
