The NGK 4‑wire air-fuel ratio sensor for Suzuki Grand Vitara (2009–2013) is a direct-fit wideband oxygen sensor that supplies a linear A/F signal so the ECU can accurately monitor and adjust the mixture for improved combustion, fuel economy and lower emissions. NTK-developed ceramic technology and a 3-stage contaminant-resistant plasma jet with deposit trap protect the element and enhance resistance to failure for reliable OE-level operation.
