The NGK five‑wire wideband air‑fuel sensor for Mazda 3 (2014–2016) provides a linear air‑fuel ratio output so the ECU can continuously tune mixture for optimal combustion, improved fuel economy and reduced emissions. NTK ceramic technology and a contaminant‑resistant plasma‑jet element with deposit‑trap overcoat increase resistance to poisoning, promote rapid heat‑up and deliver OE-style fitment backed by OEM collaboration and testing.
