The NGK direct-fit oxygen sensor for Hyundai Santa Fe (2007–2009) supplies constant closed-loop oxygen data to the engine control unit to help maintain proper air–fuel ratio, improve fuel economy and reduce emissions. Built using NTK’s OE sensor technology, it benefits from ceramic-element control and an advanced 3-stage contaminant-resistant plasma jet with a deposit-trap overcoat to protect against element poisoning.
