It's not every day that you discover you need a replacement Oxygen Sensor to fix your vehicle.

The function and purpose of Oxygen Sensor.

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 645Ci is heavily controlled by a computer which uses data collected by your oxygen sensors. Your BMW 645Ci 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 emissions from your tailpipe may be in excess of legal levels.

There's no reason to delay... fix it today.
