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

The 2019 Mercedes-Benz S-Class engine air filter sits in the engine bay airbox, and the cabin air filter is positioned behind the glove box.

This large luxury sedan uses an airbox in the engine compartment to feed clean air to its twin‑turbo 4.0L V8. The cabin filter mounts behind the glove box to scrub HVAC air before it enters the passenger area. If you prefer professional replacement in Sudbury, our team can handle both with Genuine Mercedes-Benz parts.

• Cabin air filter: behind glove box, accessed via trim panel

The engine air filter cleans intake air for combustion, while the cabin air filter cleans HVAC air for passengers.

On the 2019 Mercedes-Benz S-Class, the engine filter protects the twin‑turbo V8 and its sensors from dust and debris, supporting power and efficiency. The cabin filter captures pollen and particulates before air reaches the interior. Both are service items that should be inspected and replaced using Mercedes-Benz specifications.

• Engine filter: protects intake system and MAF sensor
• Cabin filter: improves in‑cabin air quality and airflow
• Use Genuine Mercedes-Benz filters for best fit and sealing
