2020 Mercedes-Benz A-Class Air Filter in Lynnfield, MA

It’s housed in the engine-bay airbox ahead of the engine cover, while the cabin filter sits behind the glove box.

The 2020 Mercedes-Benz A-Class uses a cartridge-style engine air filter inside a sealed airbox for the 2.0L turbocharged inline-4. The cabin microfilter is accessed from the passenger side, typically behind the glove box area. If you prefer professional service near Boston’s North Shore, our team in Lynnfield can service both filters in one visit. Use our online tool to schedule service.

• Engine filter: rectangular airbox with intake ducting in the engine bay

The engine filter cleans intake air for the 2.0L turbocharged inline-4, while the cabin filter cleans HVAC air you and your passengers breathe.

On the 2020 Mercedes-Benz A-Class, the engine air filter protects the turbocharged powertrain, helping support smooth acceleration and fuel economy rated at 24/34 mpg (city/highway). The cabin filter captures dust, pollen, and odors before they reach the interior. In New England’s pollen seasons and winter road conditions, both filters benefit from periodic inspection at Mercedes-Benz of Lynnfield.

• Engine filter: supports performance and intake system longevity
• Cabin filter: improves in-cabin air quality and HVAC airflow
• Both are OEM-replaceable elements designed for exact fit

Watch for reduced power, fuel economy falling below the EPA 24/34 mpg, rough idle, weak HVAC airflow, and musty odors.

The turbocharged engine in the 2020 Mercedes-Benz A-Class is sensitive to airflow restriction. A dirty engine filter can dull throttle response, while a clogged cabin filter causes low interior airflow and odors. If you drive through North Shore construction dust or spring pollen, inspections may be needed sooner. Book a quick check with our factory-certified team in Lynnfield.
