Shopping for BMW Oxygen Sensor

Replacing your BMW oxygen sensor is a fairly simple repair, one that you can do yourself at home with a basic tool set and a bit of self-confidence. The BMW oxygen sensor is a sensitive automotive part, and is important to keeping your combustion system at its best, as well as serving to help you reduce some of the environmentally dangerous emissions produced by the combustion engine that relies on petroleum based fuels for its power. Located within the exhaust system, immediately after the combustion system, the BMW oxygen sensor measures the amount of oxygen in the exhaust after the fuel burn. The level of oxygen remaining is an indicator of the quality of the burn, and if the quality of burn is poor, indicated by the BMW oxygen sensor finding too much oxygen present, the engine is not using the fuel as efficiently as it could. Not only does the inefficient use of fuel deprive the engine of the power that could have been gained if that fuel had been properly burned, but also produces an excess of emissions, and so the BMW oxygen sensor signals the main computer of the vehicle, which, in turn, adjusts the air-to-fuel ratio in order to achieve that better burn. A malfunctioning or failed BMW oxygen sensor is likely to end up with your vehicle running on an air-to-fuel mixture that is fuel heavy, and the excess emissions produced can cause harm to the catalytic converter, causing it to fail much sooner than it normally would, as well as cause you to spend more money for fuel as it reduces the number of miles you get to the gallon. When the air-to-fuel ratio is off, you can expect poor vehicle performance and rough running, so it is a good idea to replace your BMW oxygen sensor as soon as possible, if there is a problem with it. You can order your BMW oxygen sensor from our catalog, placing your order online or with a toll-free phone call.
