The engine air filter sits in a sealed airbox in the engine bay, while the cabin filter is typically housed behind the glove box on the 2022 Mercedes-Benz GLS-Class.

The engine airbox opens via clips or fasteners to access the panel-style filter that feeds the 3.0L inline-6 turbo. The cabin microfilter is mounted in the HVAC intake path behind interior trim. If you prefer not to remove panels, our team can perform both replacements quickly.

• Engine filter: sealed airbox in the engine bay
• Cabin filter: behind glove box/HVAC access panel
• Professional replacement available in Sudbury

The engine air filter cleans air entering the 3.0L inline-6 turbo for combustion; the cabin air filter cleans air entering the HVAC system for you and your passengers.

Keeping the engine filter clean helps maintain performance and fuel economy, while a fresh cabin filter improves in-cabin air quality and HVAC efficiency. Both are serviceable items with OEM replacements available at Mercedes-Benz of Sudbury.

• Engine filter: protects intake and sensors
• Cabin filter: reduces dust, allergens, and odors
• Genuine Mercedes-Benz replacements available

Engine filter symptoms include reduced power, lower fuel economy, or rough idle; cabin filter symptoms include weak HVAC airflow or musty odors.

If you feel the GLS-Class hesitate under load or the climate control struggles to push air, the respective filter may be saturated. A quick inspection can confirm condition and prevent downstream issues like contaminated MAF readings or blower strain.

• Engine: sluggish acceleration or poorer MPG
• Cabin: diminished airflow or persistent odors
• Schedule service for a same-visit inspection

Yes—engine filter replacement is generally DIY-friendly on the 2022 Mercedes-Benz GLS-Class, while the cabin filter often requires glove-box trim removal.

For the 2022 Mercedes-Benz GLS-Class, our air filter service focuses on accuracy, OEM fit, and system checks that protect performance and comfort. A technician begins with an engine air filter inspection, replacing the panel-style filter if it’s restricted or contaminated. The cabin microfilter is then inspected and replaced as needed to restore HVAC airflow and in-cabin air quality. We check the intake housing and seals for proper seating, and perform a visual inspection of the mass airflow (MAF) sensor area for debris or oil contamination. Old filters are properly disposed of.

The cabin air filter—positioned in the HVAC intake path behind the glove box—uses fine particulate media and, depending on configuration, may include an activated-charcoal layer for odor reduction.
