Detailed Description

This Delphi AF10381 mass air flow sensor is made for BMW vehicles that require a probe-only sensor element rather than a complete housing assembly. It measures incoming air so the engine control system can calculate fuel delivery and maintain proper drivability. This part cross-references Standard Ignition MAS0287 and Spectra Premium MA281 for the same application. Fits 2007-2013 BMW 328i, 2009-2013 BMW 328i xDrive, and other listed BMW applications with probe-only Mass Air Flow Sensors. The AF10381 is also listed for BMW 128i, Z4, 528i, 528i xDrive, X3, X5, 328xi, and 528xi applications within the stated model years.

What It Helps Address

  • Rough idle caused by inaccurate airflow readings
  • Hesitation or sluggish throttle response
  • Check engine light related to mass air flow sensor performance
  • Incorrect fuel trim from faulty air measurement
  • Driveability issues on BMW 328i, X3, X5, and related models

Installation Notes and Tips

Verify that your vehicle uses a probe-only Mass Air Flow Sensor before ordering. Match the connector shape, terminal count, and mounting style to the original part. Inspect the intake tract for leaks, contamination, or damaged wiring before installation, since those conditions can affect sensor readings. Follow the included instruction sheet and confirm the sensor seats correctly with the bolt-on design.

Quality Assurance

Delphi builds this replacement with OE-focused engineering based on more than a century of original equipment experience. That background supports consistent fitment and sensor performance for BMW mass air flow sensor replacement needs.
