2022 Mercedes-Benz CLS-Class Air Filter in Sudbury, MA

It’s housed in a sealed airbox in the engine bay, positioned ahead of the 3.0L inline-6 intake.

The airbox contains the panel-style filter that feeds clean air to the turbocharged intake of the 2022 Mercedes-Benz CLS-Class. Release the airbox fasteners to access the element and note the filter’s orientation for correct reinstallation. Avoid disturbing nearby sensors or wiring when opening the housing. If you’re unsure, book a professional inspection in Sudbury for peace of mind.

• Open hood; locate the sealed airbox
• Release clips/screws to open the lid
• Match the filter’s airflow direction on install

It sits behind the glove box in the HVAC housing, accessed from the passenger side.

The 2022 Mercedes-Benz CLS-Class uses a microfilter (often charcoal-activated) to scrub dust, pollen, and odors before air reaches the cabin. Accessing it typically requires removing the glove box stops or adjacent trim, then sliding out the rectangular filter. If trim removal or tight clearances are a concern, our Sudbury team can perform the job quickly and correctly.

• Empty glove box; release side stops
• Remove access cover on the HVAC housing
• Install new filter with arrows toward airflow

The engine filter protects the turbocharged 3.0L intake, while the cabin filter cleans air entering the passenger compartment.

In the 2022 Mercedes-Benz CLS-Class, the engine air filter is a high-flow panel that safeguards performance (362 hp, 369 lb-ft) and fuel economy by blocking dirt before it reaches the intake. The cabin microfilter targets dust, pollen, and odors to keep HVAC airflow clean and comfortable. Both are vital: one for powertrain health, the other for passenger comfort.

• Engine filter = intake protection
• Cabin filter = passenger air quality
• Both should meet OEM specifications

Engine symptoms include sluggish acceleration and lower MPG; cabin symptoms include weak airflow and musty odors.

On a 2022 Mercedes-Benz CLS-Class, a restricted engine filter can cause rough idle, hesitation, or a check-engine light if the mass airflow readings skew. A saturated cabin filter often shows as reduced fan output and lingering odors, especially after pollen season in Sudbury. If these appear, book a diagnostic and filter check promptly.

• Engine: slower throttle response
• Cabin: diminished HVAC airflow
• Odors after rain or leaves/debris

Yes—many owners DIY the engine filter, but the cabin filter often needs trim removal and is easier at the dealer.

The 2022 Mercedes-Benz CLS-Class uses a panel engine filter secured by clips or screws; careful sealing prevents unmetered air. The cabin filter sits behind glove box components that can be finicky. Dealer service adds an intake housing check and a visual MAF inspection with OEM-spec parts. If you prefer expert help, schedule service in Sudbury.

• Engine: simple tools, careful sealing
• Cabin: glove box/trim access
• Dealer adds OEM parts and inspections

Our 2022 Mercedes-Benz CLS-Class air filter service is a concise, model-informed process designed to protect both engine performance and cabin comfort. A technician begins with an intake housing check to confirm clips, seals, and ducting are intact, then removes and inspects the engine air filter for restriction or contamination. If replacement is needed, we install a Genuine Mercedes-Benz panel filter and ensure the airbox seals properly to prevent unmetered air. Next, we access the cabin microfilter behind the glove box, inspect for debris and saturation, and fit a fresh OEM-spec microfilter (particulate or charcoal, per spec). A visual MAF sensor and snorkel check help catch issues early. We dispose of old elements responsibly and road-test for HVAC and throttle response. Ready to proceed? Schedule service today.
