NTK 25718 oxygen sensor for the 2015-2017 Kia K900 V8 5.0L and other vehicles reads exhaust oxygen and sends closed-loop feedback to the ECU. This NTK oxygen sensor helps the ECU control the air-fuel ratio and lets the OBDII system flag fuel delivery or catalytic converter problems.
A check engine light, rough running or poor fuel economy can mean the sensor has worn out. An exhaust leak, a vacuum leak, damaged wiring or a fuel delivery fault can show up the same way, so trace the cause before buying a sensor.
The vehicles it fits include the 2009-2012 Hyundai Genesis V8 4.6L and the 2012-2016 Genesis V8 5.0L, and the 2011 Hyundai Equus V8 4.6L and the 2012-2016 Equus V8 5.0L; each application takes one sensor, and this listing is one. If your car is not named here, look it up in the "Vehicles it fits" section.
