BMW Mass Air Sensor & Air Flow Meters for BMW X Series E53 (2000-2006)

Clear BMW chassis

Please ensure your correct model is selected

We sell OEM air mass sensors, air flow meters, and HFMs (Hot Film Meter) for many BMWs. When the mass air sensor is bad you will notice your engine running out of tune. Your fuel mileage will suffer, throttle response will be poor, and you will notice a lack of power.

There should be a Check Engine Light to alert you that the air sensor is having problems. However, there may not be a fault code for the air meter itself. Often times the code comes up as fuel trim or lean condition. In these cases the air sensor could be just one of a number of potential problems.

We only sell air sensors from Original Equipment Manufacturers like, Bosch, VDO, and Siemens. Please note that HFMs are an electrical part and cannot be returned for refund.

This is a high quality replacment OEM VDO Mass Air Sensor.The MAF controls the amount of fuel that goes through the injectors based on the volume of air coming through the intake. If your vehicle is giving you a MAF code, replace it immediately to ensure you get the best gas mileage and performance. It is common for this part to fail slowly and cause poor fuel mileage and hampered performance. When it fails completely, the vehicle will stutter and stall as it falls into a limp mode. One way to check if your MAF is bad is to unplug the connector before starting your car. If it idles well (compared to a previous poor idle), your MAF needs replaced. If you let this maintenance part go, your fuel economy will suffer as too much fuel is going into the engine and not being burned. A great way to give your vehicle an efficiency boost.
