NGK Hyundai Sonata 2011 Direct Fit Oxygen Sensor

This is an NGK oxygen sensor, designed to fit your 2011 Kia Optima or 2011-2013 Kia Optima. Oxygen sensors are a key part of your car's onboard diagnostic system. They constantly send information to the engine control unit (ECU) about the air-fuel mixture, helping to keep your engine running smoothly, get the best possible gas mileage, and reduce harmful exhaust emissions. When an oxygen sensor isn't working right, it can also alert the system to potential issues with fuel delivery or the catalytic converter.

NGK, a ceramics company at its core, controls the manufacturing of its oxygen sensor elements from the raw materials all the way to the finished product. This advanced ceramic sensor element includes a 3-stage contaminant-resistant plasma jet and deposit trap overcoat. This design helps protect the sensor element from poisoning by contaminants, which can lead to premature failure. Because NGK works directly with OEM manufacturers from concept through production, their sensors are built to perform reliably.
