What makes the BMW M5 the "Ultimate Driving Machine" is the same precision engineering that went into its performance racing ancestors built during the 1970's. The BMW M5 is essentially a sports car, combined with the body and comfort of a luxury sedan. Like any other high performance automobile, the BMW M5 operates best within certain parameters.

Staying within these parameters requires scheduled maintenance. The BMW M5 oxygen sensor is one of the components key to engine performance and efficiency.

A certain air fuel mixture, delivered to the cylinders by the fuel injectors, keeps the engine to running at peak performance while minimizing exhaust emissions. When this mixture is "lean," i.e. containing a higher ratio of air to fuel, exhaust emissions are lower. The BMW M5 oxygen sensor detects the amount of oxygen in the exhaust gases, then delivers an electronic signal to the fuel-injection system. Fuel injectors adjust the mixture accordingly. In order for the BMW M5 oxygen sensor to operate, the vehicle must be at running temperature, so signals are not sent to the fuel injectors until the engine is at this temperature. A defective or damaged oxygen sensor can result in lower engine performance, increase fuel consumption, and polluting exhaust. These three symptoms indicate that it's time to replace your old unit with a new factory authorized BMW M5 oxygen sensor from our online catalog.
