2025 BMW 7 Series Air Filter in Sudbury, MA

The engine air filter sits in a sealed airbox within the engine bay, feeding the 4.4L twin‑turbo V8 intake.

This enclosure filters incoming air before it reaches the turbochargers and mass airflow sensor. On the 2025 BMW 7 Series, the airbox is designed to be serviceable without disturbing adjacent components. For proper sealing and flow, the gasketed lid and housing tabs should be inspected during service at Herb Chambers BMW of Sudbury.

• Engine code: 8VTTM4.4 (twin-turbo V configuration)
• Filter resides upstream of the MAF and turbo inlets
• Housing and clips should be checked for damage or debris

The engine filter protects the 4.4L V8s intake air, while the cabin filter cleans HVAC air for passengers.

The engine air filter prevents dust and debris from reaching the turbochargers and sensors, supporting performance and efficiency. The cabin filter traps pollen and particulates before air enters the interior through the climate system. Both are maintenance items, but they serve different systems and require different media and fitments.

If you notice these symptoms around Sudbury or Boston traffic, book an inspection so we can confirm the cause and restore airflow.
