2019 Mercedes-Benz GLC-Class Coupe Air Filter in Sudbury, MA

It’s in the engine bay inside a rectangular airbox near the front passenger side of the 2.0L turbocharged inline-4.

The 2019 GLC-Class Coupe uses a panel-style engine air filter housed ahead of the engine for easy access. The cabin air filter is separate, typically accessed behind the glove box. If you prefer professional service near Greater Boston, our Sudbury team can inspect and replace both filters using OEM-spec parts.

The engine air filter cleans air for combustion, while the cabin air filter cleans HVAC air you and your passengers breathe.

On the 2019 GLC-Class Coupe, the engine filter protects the turbocharger and mass airflow sensor from dust and debris. The cabin filter reduces particulates and odors inside the vehicle. Replacing both on time preserves performance and interior air quality—especially valuable in city commuting around Sudbury and Boston.

Reduced power or mpg points to a restricted engine filter; weak HVAC airflow or musty odors suggest a clogged cabin filter.
