NGK direct-fit oxygen sensor for 2001 Volvo S60. Oxygen sensors deliver continuous closed-loop feedback to the engine control unit to help preserve engine performance, improve fuel economy and reduce emissions by regulating air–fuel ratio and alerting OBDII systems to potential fuel delivery or catalytic converter problems. This NGK sensor uses an advanced ceramic element with a 3-stage contaminant-resistant plasma-jet and deposit-trap overcoat to resist poisoning.
