Product Description

This Denso Oxygen Sensor can be installed on BMW 528is from the years 1997 and 1998. An Oxygen Sensor monitors the fuel to air ratio by evaluating it to provide the highest mileage. Oxygen Sensors are essential devices that are attached to the exhaust system to improve fuel performance. Your Oxygen Sensor is a part used to check the level of oxygen in a car or truck's exhaust. The Oxygen Sensor is part of the emissions system and assists with alterations to the air to fuel ratio, removing the necessity for constant altitude adjustments. Usually found next to the exhaust manifold, your car's Oxygen Sensor passes oxygen levels present in the vehicle's exhaust system to the engine computer. A quality Oxygen Sensor measures the oxygen level which is forced into your cylinders. When the ratio of fuel to air is too lean, inadequate combustion will be the aftermath; on the other hand, a too-rich mixture can lead to harm to your motor and large quantities of pollution from your car or truck's exhaust pipe. BMW 528is of model years 1997 and 1998 will work with this Oxygen Sensor. Different vehicles are unlikely to be compatible, so this Oxygen Sensor is not intended to be installed in those models.
