The 4-wire narrow-band oxygen sensor is a replacement sensor for select 2013-2022 Infiniti, Nissan and Renault applications. It signals whether the exhaust is running rich or lean so the engine computer can trim fuel delivery. A built-in heater brings the element to operating temperature quickly after a cold start.
