现代劳恩斯酷派 2009 2.0T 氧传感器 39210-2C210 即插即用

When your Hyundai Laoness Coupe 2009 2.0T experiences unstable idle, weak acceleration, obvious fuel consumption increase, or the engine warning light staying on, this usually indicates aging/failure of the original oxygen sensor, causing air-fuel ratio imbalance. When functioning normally, this oxygen sensor monitors the oxygen content in the exhaust in real time and feeds the signal back to the ECU to precisely control the fuel injection, ensuring efficient engine combustion and compliant emissions. OEM part number 39210-2C210, fits the 2009-2012 Hyundai Lavida Coupe 2.0T models. During installation, ensure the sensor threads are clean and apply anti-seize, avoid cross-tightening, and operate with the engine cool to prevent scalding.
