2023 Mercedes-Benz G-Class Air Filter in Sudbury, MA

The 2023 Mercedes-Benz G-Class engine air filter sits in the engine bay inside a sealed airbox ahead of the 4.0L V8.

This airbox is designed to feed clean air to the intake while keeping debris away from the mass airflow pathway. Access typically involves releasing airbox clips or fasteners, then lifting the cover to reveal the rectangular filter. Keeping this housing sealed is important for proper metering and drivability. If you prefer professional service, book a visit at Mercedes-Benz of Sudbury.

• Open hood and locate the airbox forward of the engine
• Release airbox latches/fasteners to access the panel filter
• Ensure the airbox seal is properly seated during reassembly

The 2023 Mercedes-Benz G-Class cabin air filter is located behind the glove box within the HVAC housing.

On most G-Class models, accessing the cabin filter requires opening the glove box and removing a trim panel to reach the filter door. This multi-layer filter cleans incoming air for occupants and the HVAC system. If you’d rather not remove interior trim, our team can replace it quickly using genuine Mercedes-Benz parts.

• Access panel is typically behind the glove box

The engine air filter protects the 4.0L V8's intake air, while the cabin air filter cleans air for passengers and the HVAC system.

The engine filter prevents dust from entering the combustion air path, supporting smooth power (416 hp at 5,250 rpm) and efficiency with premium unleaded fuel. The cabin filter targets dust and allergens before air reaches the vents. Each filter serves a distinct system and is serviced separately.

• Engine filter = combustion air; cabin filter = passenger/HVAC air
• Different locations: airbox (engine) vs. HVAC housing (cabin)
• Both are OEM-specific parts for proper fit and sealing

Common signs include reduced power, lower fuel economy, rough idle (engine filter), and weak airflow or musty odors (cabin filter).

If the G-Class feels sluggish or returns fewer miles per gallon, the engine filter may be restricting intake air. Weak ventilation, haze on glass, or odors suggest a saturated cabin filter. Replacing both with OEM-spec parts helps restore performance and comfort. Our Sudbury team can inspect both filters during a single visit.

• Engine symptoms: hesitation, rough idle, decreased MPG
• Cabin symptoms: reduced vent airflow, odors, excess dust
• Book an inspection: schedule service

Yes—engine filters are often DIY-friendly; cabin filters may require trim removal, and dealer service adds OEM-spec parts and intake/MAF checks.

Many owners can open the airbox and swap the engine filter, but correct sealing and fit are critical. Cabin filter access behind the glove box can involve clips and tight spaces. Dealer replacement includes visual intake checks and documentation. Prefer expert help? Reserve a time online and review current offers.

Our air filter service for the 2023 Mercedes-Benz G-Class focuses on precision fitment and clean airflow. We begin by identifying your vehicle and confirming the 4.0L V8 configuration. The technician opens the intake airbox, inspects the existing engine filter for debris and seal condition, and installs a genuine Mercedes-Benz replacement if needed. Sealing surfaces and intake ducts are checked for cracks or loose clamps. A visual inspection of the mass airflow pathway helps ensure proper metering. For the cabin, we open the access panel behind the glove box, remove the used filter, clean the housing as needed, and install a fresh OEM-spec cabin filter with the correct airflow orientation. We document findings on your repair order so you can track service history. Ready to book? Use our online tool: schedule service.

The 2023 Mercedes-Benz G-Class uses two separate filters: an engine air filter for the 4.0L V8 (3,982 cc) intake and a cabin particulate filter for HVAC airflow. The engine filter lives inside a sealed airbox in the engine bay and uses a panel-style element sized for the G-Class intake volume and 416 hp output (5,250 rpm). The cabin filter—housed behind the glove box—uses multi-layer media engineered to capture dust and fine particles before air reaches the vents. Genuine Mercedes-Benz filters are designed for precise fit and effective sealing, helping the SUV maintain consistent throttle response and clean cabin air.
