NGK direct-fit oxygen sensor for 2003–2005 Jaguar S-Type. Oxygen sensors provide continuous closed-loop feedback to the engine control unit to help preserve engine performance, improve fuel economy and reduce emissions by managing the air–fuel ratio and alerting OBDII systems to fuel delivery or catalytic converter issues. This sensor features an advanced ceramic element with a 3-stage contaminant-resistant plasma-jet and deposit-trap overcoat to resist element poisoning.
