2023 Mercedes-Benz CLS-Class Air Filter in Lynnfield, MA

The 2023 Mercedes-Benz CLS-Class engine air filter sits in a sealed air box within the engine bay, and the cabin air filter is housed behind the glove box.

The engine element feeds the 3.0L inline-6 turbo (engine code 6ITCM3.0) and lives in a serviceable intake housing for quick access. The cabin microfilter is positioned behind the glove box to clean incoming HVAC air for passengers. If you prefer professional installation, our Lynnfield team can replace both filters during the same visit—simply schedule service.

• Engine filter: sealed intake air box in the engine bay
• Cabin filter: behind the glove box access panel
• Service both together for one consolidated appointment

The engine air filter protects the 3.0L inline-6 turbo’s intake, while the cabin air filter cleans the air you breathe through the HVAC system.

Under the hood, the engine filter screens dust before it reaches the turbocharger and mass air flow sensor, supporting smooth power delivery and fuel efficiency. Inside the car, the cabin filter captures fine particles and odors to improve in-cabin air quality. Each filter serves a different system and requires its own service inspection.

• Engine filter = combustion air for performance and efficiency
• Cabin filter = HVAC airflow for passenger comfort
• Different locations, different materials, separate service checks

Typical signs include reduced power and MPG for the engine filter, and weak airflow or musty odors for the cabin filter.

Because the CLS-Class makes 362 horsepower, even small intake restrictions can feel noticeable under acceleration. A dirty cabin filter often shows up as louder fan speeds with less airflow or stale smells from the vents. If you notice these symptoms, book a quick inspection in Lynnfield and review our service specials.

• Engine: sluggish response, rough idle, lower fuel economy
• Cabin: diminished HVAC airflow, dustier glass, odors
• Visible debris or discoloration on filter media
