NGK Ford Focus 2011-2003 Direct Fit Oxygen Sensor

The advanced ceramic sensor element in this NGK oxygen sensor is built with a 3-stage contaminant-resistant plasma jet and deposit trap overcoat. This design helps protect the element from poisoning, which is crucial for maintaining optimal engine performance. As a vital part of your vehicle's on-board diagnostic system, oxygen sensors like this one help control the air-fuel ratio by providing constant feedback to the ECU. This not only maximizes fuel efficiency but also helps reduce harmful emissions and alerts the OBDII system to potential issues with fuel delivery or the catalytic converter.

NTK, a leading supplier of OEM oxygen sensors, works closely with manufacturers from concept to production to ensure their designs offer excellent performance and improved resistance to failure. This direct-fit sensor is designed to install easily and function correctly within your 2003-2011 Ford Focus, helping to keep your engine running smoothly and efficiently.
