The NGK direct-fit oxygen sensor for Hyundai Santa Fe (2003–2004) supplies constant closed-loop feedback to the engine control unit to aid air–fuel ratio management, fuel efficiency and emissions control. NTK's sensor expertise yields a ceramic element with a 3-stage contaminant-resistant plasma jet and deposit-trap overcoat to protect against element poisoning, and the design is developed with OEM manufacturers for OE application reliability.
