The NGK direct-fit oxygen sensor for Cadillac Eldorado (1979–1980) supplies continuous closed-loop feedback to the engine control unit to help control air–fuel ratio, improve fuel efficiency and reduce emissions. Leveraging NTK ceramic sensor development, the unit uses an advanced ceramic element with a 3-stage contaminant-resistant plasma-jet and deposit-trap overcoat to protect the sensor from element poisoning and support OE application practices.
