Give your BMW's fuel management the accurate airflow signal it depends on with the Standard Ignition Mass Air Flow Sensor MAS0470. This sensor measures the mass of air entering the engine and reports it to the ECU, which uses that reading to command the correct air/fuel ratio. It drops in as a direct-fit replacement for many 2013-2019 BMW models with the V8-4.4L engine, including the 550i, 550i GT, 650i, 650i Gran Coupe, 750i, 750Li, ALPINA B6 xDrive Gran Coupe and X5 — see the Buyer's Guide tab for the full list.
- 100% new, never remanufactured: no leftover debris that can cause sensor failure.
- Computer-tested: 100% tested so the ECU receives accurate airflow readings needed to deliver the correct air/fuel ratio.
- Proprietary sensing elements: designed to provide accurate airflow output to the ECU across a wide range of ambient temperatures.
- Sensor only: housing not included; plastic-bodied unit bolts on through two bolt holes with a single oval female connector and four male pin terminals.
If a faulty mass air flow sensor is behind symptoms such as rough idle, hesitation, poor fuel economy or a check engine light, this unit replaces it. Diagnose the cause before replacing. Made in Germany. Manufacturer part number MAS0470.
