NGK direct-fit oxygen sensor for 1999–2002 Daewoo Nubira. Oxygen sensors supply continuous closed-loop feedback to the ECU, helping keep engine performance optimal, improve fuel efficiency and reduce emissions by managing air–fuel ratio and notifying OBDII systems of fuel delivery or catalytic issues. The sensor incorporates an advanced ceramic element with a 3-stage contaminant-resistant plasma-jet and deposit-trap overcoat to enhance resistance to element poisoning.
