The NGK OE‑type 4‑wire air/fuel sensor for 2021–2024 Lexus ES250 models is an OE‑style replacement that restores accurate air–fuel ratio sensing for the engine control system. Matching original connector and wiring configuration, it supplies the necessary signal for fuel‑trim and emissions monitoring and installs in the same location as the factory sensor.
