The 4-wire narrow-band oxygen sensor is a replacement sensor for 2010-2016 Porsche Panamera with the 3.0L V6, 3.6L V6 or 4.8L V8 engines in the downstream position. 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.
