The NGK direct-fit oxygen sensor for Chevrolet Classic (2004–2005) provides the engine control unit with continuous closed-loop input to help manage air–fuel ratio, boost fuel efficiency and reduce emissions. Employing NTK ceramic sensor expertise, the sensor includes a 3-stage contaminant-resistant plasma-jet and a deposit-trap overcoat to protect the ceramic element from poisoning and support OE application standards.
