The NGK 4-wire air–fuel (A/F) sensor for Nissan Altima (2011–2013) provides a wideband output that allows the ECU to measure exact air–fuel ratios for precise mixture control, improved combustion and lower emissions. It leverages NTK wideband ceramic technology and includes a 3-stage contaminant-resistant plasma jet with deposit-trap overcoat to protect the element from poisoning. NTK's work with OEMs supports reliable, accurate sensor performance.
