The NGK OE‑type 4‑wire air/fuel sensor for 2011–2014 Mazda 2 models is a direct OE replacement that restores proper air–fuel ratio monitoring for engine management. Matching the original sensor’s wiring and fitment, this four‑wire A/F sensor provides the signal needed for fuel‑trim and emissions systems and installs like the factory unit to correct sensor‑related issues.
