The NGK five‑wire wideband air‑fuel sensor for Hyundai Elantra (2007–2009) delivers a linear A/F output so the ECU can continuously refine fuel mixture for better combustion, fuel economy and lower emissions. Leveraging NTK ceramic expertise, the sensor includes a 3‑stage contaminant‑resistant plasma‑jet element with a deposit‑trap overcoat to resist element poisoning, heat quickly and provide OE-style fit and reliability.
