2015 Mercedes-Benz GLA-Class Air Filter in Sudbury, MA

The engine air filter sits in the engine bay inside a rectangular airbox ahead of the turbo inlet, while the cabin filter is typically behind the glove box.

This layout routes clean air to the 2.0L turbo inline-4 before it reaches the intake tract. The cabin filter helps scrub dust and allergens before air enters the HVAC system. If you prefer professional help in Sudbury, you can schedule service at Mercedes-Benz of Sudbury for an OEM-spec replacement and a quick fit-check of the airbox clips and seals.
