The engine air filter sits in a sealed air box within the engine bay.

On the 2021 Mercedes-Benz G-Class, the air box is mounted under the hood and feeds the 4.0L twin‑turbo V8’s intake. The cover is secured with clips or fasteners; replacing the element requires careful resealing to prevent unmetered air leaks. If you’d like a quick, OEM-spec swap, schedule service with us.

• Under-hood sealed air box
• Cover fasteners/clips secure the lid
• Proper sealing protects MAF readings

The engine air filter protects the 4.0L twin‑turbo V8’s intake, while the cabin air filter cleans HVAC air for passengers.

The engine filter stops dust before it reaches the turbochargers and mass airflow sensors, supporting power and fuel economy. The cabin filter traps pollen, dust, and odors so the interior stays pleasant. Replacing both on time keeps the 2021 Mercedes-Benz G-Class performing and your cabin comfortable.

• Engine filter = combustion air protection
• Cabin filter = interior air quality
• Both are OEM-replaceable maintenance items

Typical signs include reduced power, lower fuel economy, rough idle, weak HVAC airflow, and musty odors.

A dirty cabin filter often shows as noisy fans with little airflow or lingering smells. If you spot these symptoms around Sudbury or Greater Boston, schedule service for a quick check.

• Sluggish acceleration or rough running
• HVAC airflow weak or noisy
