The NGK direct-fit oxygen sensor for Ford Crown Victoria (2006–2011) replaces the factory-installed unit and provides continuous closed-loop OBDII feedback to the engine control unit to help maintain optimal engine performance, fuel efficiency and emissions monitoring. It uses refined ceramic sensor construction with a 3-stage contaminant-resistant plasma jet and deposit-trap overcoat to shield the element from poisoning and enhance service life and OE compatibility.
