2025 Mercedes-Benz G-Class Air Filter in Sudbury, MA

The 2025 Mercedes-Benz G-Class engine air filter sits inside a sealed airbox in the engine bay.

The airbox feeds the 3.0L inline-6 (engine code 6ITWM3.0) and opens after releasing its clips or fasteners. Access is straightforward, but correct gasket seating is essential to prevent unfiltered air from entering the intake. If you prefer a quick professional check, our Sudbury team can inspect the housing and mass airflow (MAF) area.

• Reseat the airbox seal carefully
• Schedule service for an intake check

The 2025 Mercedes-Benz G-Class cabin air filter is typically behind the glove box, accessed via an interior panel.

This filter cleans HVAC air for passengers and catches dust and pollen common around Greater Boston. Trim clips or screws may need removal to reach the filter door. Our technicians in Sudbury can replace it and verify proper airflow and blend-door operation.

The engine air filter protects the 3.0L inline-6 intake, while the cabin air filter cleans HVAC air for passengers.

On the 2025 Mercedes-Benz G-Class, the engine filter supports performance and fuel quality for the premium-unleaded (required) powertrain, and the cabin filter captures particulates inside the SUV. Each filter lives in a different location and serves a distinct purpose.

• Engine: intake protection and performance
• Cabin: dust, pollen, and odor reduction
• Separate service intervals and access points

Common signs include reduced power or lower fuel economy for the engine, and weak airflow or musty odors in the cabin.

If the engine air filter is restricted, the 3.0L inline-6 may feel sluggish, idle roughly, or trigger a warning. A dirty cabin filter can make the HVAC struggle and circulate stale air. In Sudbury, periodic checks help catch issues early.

• Engine: hesitation, rough idle, poorer MPG
• Cabin: weak vents, odors, more fogging
• Schedule an inspection for confirmation

Yes—the engine filter is often DIY-friendly, while the cabin filter may require trim removal; dealer service adds intake and MAF checks.
