BMW Mass Air Sensor & Air Flow Meters for BMW 7 Series E66 (2002-2008)

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 the replacement mass air sensor to fit the N62 engine used in the E60 545i, E63 645ci, E65 745i/Li, and E53 X5 4.4i/4.8is. This HFM is manufactured by OEM supplier Bosch and is a direct replacement for the stock HFM. When the HFM goes bad there should be a fault code and check engine light. In addition, your fuel economy will usually go down as the computer is no longer getting a good signal of airflow and the safest thing for the computer to do is add fuel. Replacement is straight-forward and easy with simple hand tools.

This item fits the following BMWs:
2004-2005 E60 BMW 545i
2004-2005 E63 BMW 645ci
2002-2005 E65 BMW 745i 745li
