The NGK direct-fit oxygen sensor for Hyundai Elantra (1998–2000) supplies constant closed-loop feedback to the ECU to help control air–fuel ratio, fuel economy and emissions. Built with NTK sensor know-how, this replacement uses an advanced ceramic element and a 3-stage contaminant-resistant plasma jet and deposit trap overcoat to improve resistance to element poisoning and premature failure.
