The oxygen sensor installs on 2002-2005 Chevy Zafira, 2016 Chevy Cruze, 2009-2019 Porsche 911 and 2015 Porsche 918 Spyder. 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.
