Detailed Description

The Delphi AF10420 mass air flow sensor is built for BMW and Mini vehicles that use a probe-only MAF configuration. It measures incoming air so the engine control system can calculate fuel delivery more accurately, which is important for drivability on applications such as the BMW 320i, BMW X1, BMW M4, and Mini Cooper. Delphi’s OE heritage and supplier experience are reflected in the sensor’s standard replacement design and direct-fit electrical layout. This part cross-references Standard Ignition MAS0338 for the same application.

Common Issues It May Address

  • Rough idle caused by inaccurate airflow readings
  • Hesitation or stumble during acceleration
  • Check engine light related to airflow sensor performance
  • Poor fuel trim behavior from a failing MAF sensor
  • Reduced throttle response on BMW and Mini probe-only applications

Installation Notes

Confirm the vehicle uses a probe-only mass air flow sensor before ordering. This unit uses a 4-terminal blade connection, 1 female oval connector, and bolt-on mounting. Housing and wiring harness are not included, so reuse the existing components where applicable. Verify connector shape, terminal count, and OE part match before installation on BMW M2, BMW X5, or Mini Cooper applications.

Quality Assurance

Delphi builds this replacement sensor using OE-level engineering knowledge developed through long-term supplier experience with major automakers. The AF10420 is intended as a standard replacement part for the listed BMW and Mini fitments, including 2012-2021 applications across the range shown.

This part fits 129 vehicles
Always verify fitment with your vehicle's VIN if unsure. Submodel & trim restrictions may apply.
