BMW Oxygen Sensor - Bosch 13231

 

If your car's engine triggers the oxygen sensor check engine light, replace it with this high-quality unit. The O2 sensor accurately measures the unburned fuel in the exhaust pipe, allowing for optimized fuel mapping and reduced emissions. If the sensor malfunctions, your MPG and overall performance may be compromised. However, this can be easily remedied by replacing the sensor and applying anti-seize on the threads to prevent it from becoming fused to the exhaust. It is important to keep up with regular maintenance since these sensors tend to have gradual failures over time.
