The NGK 5‑wire wideband air‑fuel sensor for Hyundai Sonata (2011–2014) is a direct‑fit oxygen sensor supplying linear air‑fuel data so the ECU can continuously tune mixture for improved combustion, fuel efficiency and emissions control. Built with NTK/NGK ceramic know‑how, it employs a 3‑stage contaminant‑resistant plasma jet and deposit‑trap overcoat to protect the sensing element and increase resistance to failure.
