Are you looking for a fine-tuned, well-oiled vehicle? Well, you can’t have that without a quality oxygen sensor. Your Mercedes S320 Oxygen Sensor is an important part of your emissions control system. A properly functioning oxygen sensor will keep engine running as efficiently as possible while simultaneously minimizing emissions.

This means fewer stops at the gas station and cleaner air in the atmosphere. Not bad for a simple oxygen sensor, eh? You see, the gasoline in your engine burns in the presence of oxygen.

There happens to be an exact ratio of oxygen to gasoline that provides maximum efficiency. If you have more oxygen than required (called a lean mixture) produces nitrogen-oxide pollutants, and may even lower the performance of your vehicle. Too little oxygen (called a rich mixture) and there is unburned fuel leftover after combustion that could create pollution as well. Your Mercedes S320 Oxygen Sensor, attaches to the exhaust pipe where it can properly monitor your car’s emissions. From here, it can tell if you are emitting a mixture that is either to rich or lean, and signals adjustments to change the amount of fuel entering the engine. This constant regulation is required because the amount of oxygen entering the engine is dependant on numerous variables that include such things as altitude, temperature and barometric pressure. These variables can require constant adjustments by the oxygen sensor. This is why a quality oxygen sensor is so important.This Mercedes S320 Oxygen Sensor is manufactured with original equipment quality for long-lasting, reliable results that you can count on for maximum efficiency.
