The NGK 5‑wire wideband air‑fuel sensor for Mazda 3 (2010–2013) is a direct‑fit oxygen sensor supplying linear A/F feedback so the ECU can precisely adjust mixture for optimal combustion, fuel economy and reduced emissions. It uses NTK/NGK advanced ceramic element technology with a 3‑stage contaminant‑resistant plasma jet and deposit‑trap overcoat to protect the sensing element and improve resistance to poisoning and failure.
