2019 Mercedes-Benz C-Class Air Filter in Sudbury, MA

The 2019 Mercedes-Benz C-Class engine air filter sits inside the engine-bay airbox, while the cabin air filter is positioned behind the glove box.

The engine air filter feeds the turbocharged 2.0L inline-4 intake, so it’s housed in a sealed airbox designed to keep debris out. The cabin filter sits in the HVAC air path, commonly accessed by lowering or removing the glove box trim. If you prefer professional installation, our Sudbury team can confirm location by VIN and perform an intake housing check during service.

On a 2019 Mercedes-Benz C-Class, the engine filter helps protect the 2.0L turbo inline-4 and supports performance and fuel economy. The cabin filter targets dust and particulates so interior air stays fresher. Both are service items, but they live in different systems and use different media. Our Sudbury service team installs OEM-spec filters matched to Mercedes-Benz standards.
