2011 Mercedes-Benz R-Class Air Filter in Sudbury, MA

The engine air filter sits in a sealed airbox in the engine bay, while the cabin filter is typically behind the glovebox.

The 2011 Mercedes-Benz R-Class uses a V-configured 3.5L V6, and its primary intake filter lives in the underhood airbox designed to feed the engine clean air. The cabin microfilter is generally accessed from the passenger side, behind or near the glovebox panel. If you prefer professional service, you can schedule service at Mercedes-Benz of Sudbury for quick, OEM-spec replacement.

• Engine filter: sealed airbox underhood with clip/fastener retention
• Cabin filter: glovebox-adjacent housing inside the dashboard area
• Sudbury location: 141 Boston Post Road, Route 20

On the 2011 Mercedes-Benz R-Class, the engine air filter supports performance and efficiency by keeping debris out of the naturally aspirated intake.
