The NGK 5‑wire wideband air‑fuel sensor for Mazda 5 (2012–2015) is a direct‑fit oxygen sensor that provides linear A/F output allowing the ECU to continuously tune mixture for improved combustion, fuel economy and lower emissions. The sensor benefits from NTK/NGK ceramic development, including a 3‑stage contaminant‑resistant plasma jet and deposit‑trap overcoat to guard the element and enhance durability.
