2026 Mercedes-Benz GLA Air Filter in Sudbury, MA

The engine air filter sits in the engine bay inside a sealed airbox ahead of the engine; the cabin filter is typically behind the glove box.

This location allows the 2026 Mercedes-Benz GLA 2.0L inline-4 to draw filtered intake air while protecting the mass airflow pathway. The cabin microfilter cleans the air entering the HVAC system for passengers. If you’re unsure, our team at Mercedes-Benz of Sudbury can confirm placement and replace both with OEM-spec parts. You can also schedule service online.

• Engine air filter: airbox ahead of the engine in the bay
• Cabin microfilter: access panel behind/near the glove box
• Seals must seat correctly to prevent unfiltered bypass

The engine air filter protects the 2.0L inline-4 intake from debris, while the cabin air filter cleans the air your passengers breathe through the HVAC system.

On the 2026 Mercedes-Benz GLA, the engine element supports performance and smooth idle, and the cabin microfilter helps keep the interior air fresher. Both are serviceable items and benefit from OEM-spec materials and proper housing seals. If you need guidance, check your maintenance booklet or book a visit in Sudbury.
