The NGK OE‑type 4‑wire air/fuel sensor for 2006–2011 Honda Civic models is a direct OE replacement that restores accurate air–fuel ratio sensing for the engine control unit. With the factory‑style four‑wire connection and fitment, it supplies the signal necessary for fuel‑trim and emissions monitoring and installs in the same location as the original sensor.
