The Kooks 12-inch Oxygen Sensor Extension Harness is designed for 2019-2020 Ram 1500 trucks equipped with the 5.7L HEMI to provide proper oxygen sensor reach when installing aftermarket headers. Featuring a 4-pin flat connector, this extension harness allows the factory O2 sensor wiring to properly connect when header installations relocate the sensor position. Built for reliability and accurate sensor communication, the harness helps maintain proper engine management system function. While extension harnesses are typically included with Kooks header kits when required, this part is intended as a replacement for damaged or missing O2 sensor extensions.
