BMW 545i Oxygen Sensor

Why you drive your 545i.

It's not all the time that you realize that you have to buy a replacement Oxygen Sensor to repair your car or truck. You purchased your 545i because its sporty handling and European styling appealed to your senses; so why would you be okay with anything but the best when it comes to great quality auto parts? Car aficionados know that a reliable name is built into each BMW, and know that only top quality repair 545i parts will suffice when maintenance needs to be done. Obviously, you bought your 545i because you knew that you wanted long-lasting quality and dependability both impeccably combined into one car, truck, or SUV.

Don't go too long without fixing your Oxygen Sensor... here's why.

Getting the most out of your car or truck depends on how well you maintain your engine and exhaust parts. The fuel-injection system on your BMW 545i is heavily controlled by a computer which uses data collected by your oxygen sensors. Your BMW 545i oxygen sensors use the particulates in the exhaust gas to determine if the fuel is too rich, too lean, or if the catalytic converter isn't working. When oxygen sensors fail your engine will not be operating as it should; lacking in power and lowering gas mileage, and it will likely be emitting an excess of hazardous exhaust.

High quality parts, lowest prices, experienced automotive professionals.
