The NGK OE‑type 4‑wire air/fuel sensor for 2006–2011 Honda Civic models is a direct replacement that restores proper air–fuel ratio monitoring for engine management. As an OE‑style A/F sensor, it fits like the original and provides the necessary signal for fuel trim and emissions control systems, making it a straightforward service item when the factory sensor fails.
