Consumer vehicles have been required to include an oxygen sensor ever since the early 1980s. Your VW Beetle is no different. But why is an oxygen sensor necessary? Well, your VW Beetle Oxygen Sensor has the important duty of maximizing the proper ratio of emissions that occur through the combustion process in the engine.

In other words, your oxygen sensor reduces the amount of toxic emissions produced by your vehicle and increases gas mileage. It does this by sensing the ratio of oxygen to gas that is being burned during combustion.

This ratio is integral because fuel must be in the presence of oxygen to burn, and there happens to be a specific ratio that maximizes performance. If there is too much oxygen mixing with the fuel, than you have what is called a lean mixture. A lean mixture may create nitrogen-oxide pollutants that damage our atmosphere and your car. Too little oxygen mixing with the fuel will result in what is called a rich mixture. A rich mixture leaves unburned gas behind after combustion. This gas is wasted, which reduces your car’s efficiency. This will require more stops at the gas station, and no one wants that. Factors such as altitude, temperature and barometric pressure can cause variations in the amount of oxygen entering the engine. This means that the oxygen sensor is making constant adjustments. To ensure an optimal mixture of oxygen to gas at all times, you need a quality oxygen sensor.This VW Beetle Oxygen Sensor was manufactured to original equipment quality to give you maximum performance and long-lasting results.
