The NGK direct-fit oxygen sensor for Chevrolet Optra (2006–2007) provides closed-loop feedback to the ECU to assist air–fuel ratio management, fuel efficiency and emissions control. NTK-developed ceramic element technology includes a 3-stage contaminant-resistant plasma jet and deposit-trap overcoat that helps resist element poisoning, and the sensor design is refined with OEM manufacturers to improve resistance to failure in OE replacement use.
