BMW Mass Air Sensor & Air Flow Meters for BMW Z Series E85/6 (2003-2008)

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.

Ensure your vehicle maintains optimal fuel efficiency and performance by swiftly replacing the Mass Airflow Sensor (MAF). This crucial component regulates fuel delivery through injectors based on incoming air volume. A faulty MAF can significantly impact gas mileage and overall performance.

Gradual MAF failure often results in reduced fuel efficiency and performance degradation. Complete failure may cause stuttering and stalling, forcing the vehicle into a limp mode. A simple diagnostic test involves unplugging the MAF connector before starting the car; improved idling indicates a faulty MAF requiring replacement.

Failure to replace the MAF leads to excessive fuel consumption and inefficient burning, adversely affecting fuel economy. Opt for a Genuine BMW MAF replacement to ensure stock-quality performance and enhance vehicle efficiency.
