The NGK direct-fit oxygen sensor for Hyundai Accent (1997–1999) helps the vehicle’s OBDII system monitor catalytic converter efficiency and air–fuel mixture by providing reliable closed-loop feedback to the ECU. Leveraging NTK sensor development, this replacement uses an advanced ceramic element with a 3-stage contaminant-resistant plasma jet and deposit trap overcoat to resist element poisoning.
