BMW 3-Series Oxygen Sensor
Car emissions are important environmental concerns. The 3-Series oxygen sensor is one of the key elements in your car that maintains the oxygen and fuel balance of your vehicle. When there isn't enough O2 in the mixture, it's a rich fuel environment and creates excess carbon monoxide.
