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

The engine air filter sits in a rectangular airbox in the engine bay, ahead of the 2.0L turbo intake on the passenger side (U.S.-spec models).

This housing feeds the 2.0L inline-4 turbo (engine code 4ITCG2.0) and is secured with clips or screws for a sealed fit. Accessing this airbox allows quick inspection and replacement without disturbing other major components. While you’re servicing it, the cabin filter location is separate—typically behind the glovebox.

• Feeds the 2.0L inline-4 turbo (4ITCG2.0)

The engine air filter protects the 2.0L turbo intake from debris, while the cabin air filter cleans HVAC air for passengers inside the car.

Under the hood, the engine filter helps maintain performance and efficiency by screening dust before it reaches the turbocharger and MAF sensor. Inside the vehicle, the cabin filter traps particulates entering through the HVAC system, commonly accessed behind the glovebox. Both are maintenance items, but they serve different systems and have different access points.

• Engine filter: intake protection for combustion
• Cabin filter: interior air quality via HVAC

Common signs include reduced power, lower fuel economy, rough idle (engine filter), weak HVAC airflow, and musty odors (cabin filter).

On the 2.0L inline-4 turbo, an overly dirty engine filter can restrict intake flow and affect drivability. A clogged cabin filter can make the blower work harder and diminish comfort. If you notice these symptoms around Sudbury or Greater Boston, have both filters inspected promptly to prevent avoidable wear and discomfort.

• Cabin: poor airflow or interior odor
