NGK direct-fit oxygen sensor for 1998–2000 Mercedes-Benz C43 AMG. Oxygen sensors supply continuous closed-loop feedback to the ECU, helping maintain engine performance, increase fuel efficiency and reduce emissions by regulating air–fuel ratio and alerting OBDII systems to delivery or catalytic converter issues. This sensor incorporates an advanced ceramic element with a 3-stage contaminant-resistant plasma-jet and deposit-trap overcoat to improve resistance to element poisoning.
