2019 Mercedes-Benz GLS-Class Air Filter in Lynnfield, MA

The 2019 Mercedes-Benz GLS-Class engine air filter sits in a sealed airbox within the engine bay, ahead of the 3.0L twin‑turbo V6 intake.

This airbox is designed to feed the 362‑hp, 369‑lb‑ft V6 clean air before it reaches the turbochargers and mass airflow sensor. Access typically involves unclipping or unscrewing the airbox lid and removing the old panel filter. If you prefer professional service, our Lynnfield team can inspect the intake tract and sensors during replacement.

• Located in the engine bay’s airbox ahead of the intake
• Protects turbos and MAF sensor from dust and debris
• Available same‑visit replacement at Mercedes-Benz of Lynnfield

The 2019 Mercedes-Benz GLS-Class cabin air filter is typically located behind the glove box, inside the HVAC housing.

Access usually requires opening the glove box and removing a trim cover to reach the rectangular filter that cleans incoming air for the climate control system. A fresh cabin filter helps reduce allergens and odors—useful for North Shore commutes and Boston traffic. Our technicians replace it using genuine Mercedes-Benz filters for proper fit and airflow.

• Positioned behind the glove box in the HVAC housing
• Improves HVAC airflow and reduces pollen and dust
• Professional fitment ensures sealing and quiet operation

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

On a 2019 Mercedes-Benz GLS-Class, the engine filter protects the 3.0L twin‑turbo V6 and sensors from grit, supporting power and efficiency. The cabin filter traps dust and pollen before air reaches the vents, improving interior air quality. Both are distinct parts with different locations, service steps, and performance impacts.

• Engine filter = intake air for the V6; cabin filter = HVAC air
• Different housings: airbox in engine bay vs. HVAC case
• Both affect comfort, drivability, and component longevity

Common signs include reduced power, lower MPG, and rough idle (engine filter) plus weak HVAC airflow and musty odors (cabin filter).

If your 2019 Mercedes-Benz GLS-Class feels sluggish or the air conditioning struggles to push air, one or both filters may be restricted. Local driving with construction dust or leaf debris can accelerate loading. Our Lynnfield service team can inspect the intake housing and HVAC case and replace filters with OEM parts.

• Engine: hesitation, poor fuel economy, unusual intake noise
• Cabin: weak airflow, foggy windows, persistent odors
• Inspection available during your scheduled appointment
