Oxygen sensors are a relatively recent addition to our cars. They weren't even invented thirty years ago. Back in when gasoline was thirty cents a gallon, nobody thought too much about where gasoline came from or where it was going after it was burned.

Times have changed, and so have the cars we drive. With fuel economy and hydrocarbon emissions a serious issue throughout the world, the Subaru Legacy Oxygen Sensor has become an important key to efficient fuel use and control of emissions.

The oxygen sensor has essentially taken over the function of the old choke knob. There is an ideal balance of fuel to air, called the "mixture," which maximizes engine power and minimizes exhaust emissions. A leaner mixture (less fuel and more air) equals the emissions. Some conditions, such as a heavy load, or cold weather often requires a richer mixture. The Subaru Legacy Oxygen Sensor measures the amount of oxygen in the exhaust, literally "sensing" oxygen levels. It then sends an electronic signal to the fuel-injection system based on this data. The injectors adjust the mixture for the current conditions. A damaged oxygen sensor can reduce engine performance and increase fuel consumption, as well as resulting in greater amounts of polluting exhaust. If this sounds like your car, installing a new Subaru Legacy Oxygen Sensor may cure what ails it. We offer the lowest prices on a complete line of genuine Subaru Legacy parts, and will meet or beat any competitor's prices.
