The NGK direct-fit oxygen sensor for Acura NSX (1997–1999) provides continuous closed-loop air–fuel feedback to the ECU to help maintain engine performance, improve fuel economy and manage emissions. Built by NTK, the sensor features controlled ceramic element production and a 3-stage contaminant-resistant plasma jet plus deposit-trap overcoat to reduce element poisoning and improve resistance to failure in OE applications.
