The NGK direct-fit oxygen sensor for Hyundai Santa Fe (2003–2006) provides the ECU with closed-loop feedback to help control air–fuel ratio, support fuel efficiency and limit emissions. NTK's ceramic sensor element features a 3-stage contaminant-resistant plasma jet and deposit-trap overcoat to resist element poisoning, and the sensors are developed with OEM manufacturers to improve resistance to failure in OE-style replacement applications.
