Kuga 3.0L Front Oxygen Sensor 5L8Z-9F472-AA OEM Specification Replacement

If your LHC Tiggo/Torres (Wing) 3.0L shows rough idle, rising fuel consumption, or MIL stays on, especially with exhaust odor, this usually indicates the primary O2 sensor aging or failure, unable to accurately monitor oxygen content. The sensor normally monitors exhaust oxygen content in real time and feeds signal to ECU to control fuel injection. Suitable OEM number 5L8Z-9F472-AA for Escape 3.0L models. Use a special socket to avoid thread damage; ensure sensor wiring does not contact exhaust or underbody parts to prevent heat damage.
