NGK direct-fit oxygen sensor for 1998–2000 Mercedes-Benz C43 AMG. Oxygen sensors provide continuous closed-loop feedback to the engine control unit to help maintain engine performance, optimize fuel economy and reduce emissions by controlling the air–fuel ratio and alerting OBDII systems to fuel delivery or catalytic converter problems. This sensor includes an advanced ceramic element with a 3-stage contaminant-resistant plasma-jet and deposit-trap overcoat to guard against element poisoning.
