Mass Air Flow (MAF) Sensor

Product Details

When it comes to maintaining peak performance in your BMW, clean and accurate intake metering is crucial. A worn-out MAF sensor sends inaccurate air data to your engine software, leading to lost horsepower, hesitated power delivery, and poor fuel mileage. If you are chasing hesitation under load or air-mass faults on your N51, N52, or N53 naturally aspirated inline-six, replacing your airflow sensor is one of the most effective ways to restore factory drivability.

This Febi Bilstein replacement MAF sensor insert provides OE-level precision and durability. Built using advanced hot-film element technology, it ensures your ECU gets the precise intake data required for optimal ignition timing and fuel delivery. Supplied as a standalone sensor element with a fresh sealing ring, it easily inserts into your stock intake housing, providing a cost-effective alternative to complete housing assemblies.
