The NGK direct-fit oxygen sensor for Hyundai Santa Fe (2003–2006) supplies constant closed‑loop feedback to the engine control unit to help control air–fuel ratio, support engine performance, improve fuel economy and reduce emissions. NTK’s OEM manufacturing and ceramic expertise drive sensor improvements; its 3‑stage contaminant‑resistant plasma‑jet element and deposit‑trap overcoat reduce element poisoning and increase resistance to failure for improved service life.
