Hyundai Santa Fe Oxygen Sensor 39210-37540 Stainless Steel Housing Durable

When your Hyundai Santa Fe exhibits engine warning light, higher fuel consumption, acceleration weakness, or unstable idle, the oxygen sensor may be aging or failed. The sensor provides real-time feedback to the ECU to maintain optimal air-fuel ratio, reducing emissions and boosting power. Fits Hyundai Santa Fe (2006-2012); OEM number: 39210-37540. Use a dedicated sleeve to remove the old sensor; avoid damaging threads; operate on a cold engine; clear codes after installation and allow the vehicle to relearn.
