BMW Mass Air Sensor & Air Flow Meters

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.

The Manifold Absolute Pressure (MAP) sensor plays a critical role in engine performance by providing essential data to the engine control unit (ECU). This data helps the ECU determine the optimal fuel curve for efficient combustion. A faulty MAP sensor can lead to improper fuel delivery, causing the engine to run rich or lean and resulting in reduced performance or drivability issues.

Replace your MAP sensor with this high-quality unit to ensure your engine operates at its full potential.

Note for N54 applications: An adapter harness (ES#3969322) is required. This TMAP sensor is ideal for high-boost setups commonly used with the N54 engine platform.
