The NGK 4-wire air–fuel (A/F) sensor for Lexus HS250h (2010–2012) provides a wideband output that lets the ECU measure exact air–fuel ratios for precise mixture control, better combustion and reduced emissions. It uses NTK's ceramic sensor technology and a 3-stage contaminant-resistant plasma jet with deposit-trap overcoat to resist element poisoning. NTK's collaboration with OEMs supports consistent fit and dependable long-term operation.
