The NGK direct-fit oxygen sensor for Lexus LS400 (1990–1994) gives the vehicle's ECU precise closed-loop air–fuel information to support engine performance, fuel economy and emissions monitoring. Built by NTK, the sensor uses tightly controlled ceramic element production and a 3-stage contaminant-resistant plasma jet plus deposit-trap overcoat to protect against element poisoning and improve long-term reliability in OE applications.
