The NGK 5‑wire wideband air‑fuel sensor for Mitsubishi Lancer (2011–2012) is a direct‑fit oxygen sensor that supplies linear A/F feedback so the ECU can precisely control mixture for optimal combustion, fuel efficiency and reduced emissions. The sensor features NTK/NGK ceramic engineering with a 3‑stage contaminant‑resistant plasma jet and deposit‑trap overcoat to protect the sensing element and increase resistance to failure.
