2012 Mercedes-Benz S-Class Air Filter in Sudbury, MA

The engine air filter sits inside a sealed airbox in the engine bay, ahead of the 6.0L twin‑turbo V12 intake ducts.

This airbox location lets the filter screen incoming air before it reaches the mass airflow sensor and turbochargers. On a 2012 Mercedes-Benz S-Class, access typically involves releasing housing clips and lifting the cover to remove the panel filter. If you prefer professional help in Sudbury, our technicians can confirm fitment and re-seal the housing to prevent unmetered air leaks.

• Look for a rectangular airbox with clips in the engine bay near the fenders.
• Cabin air filtration is separate and located inside the HVAC system, not the engine bay.
• Not sure? Schedule service and we’ll verify placement and fit.

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

On the 2012 Mercedes-Benz S-Class, the engine filter protects the 12VTTG6.0 V12 and its sensors by capturing dust before it reaches the intake.
