NGK direct-fit oxygen sensor for 1988–1989 Dodge D100 supplies continuous exhaust oxygen feedback to the vehicle ECU to help control the air–fuel ratio, improve fuel economy and reduce emissions. The sensor is built around an advanced ceramic element and includes a three-stage contaminant-resistant plasma-jet and deposit-trap overcoat to protect the sensing surface from contaminants and reduce the risk of element poisoning.
