2025 Mercedes-Benz GLS-Class Air Filter in Lynnfield, MA

It sits in the engine bay inside a sealed airbox near the front of the 2025 Mercedes-Benz GLS-Class.

The GLS-Class uses a 3.0L inline-6 turbo engine, so its panel-style filter lives in a dedicated airbox ahead of the intake tract for the 375-hp powerplant. Access typically involves releasing fasteners on the airbox lid and lifting the cover straight up. If you prefer professional service, our team at 385 Broadway in Lynnfield can inspect, replace, and reseal the housing correctly.

• Open the hood and look for a rectangular airbox toward the front of the engine bay.
• Release clips/screws, lift the lid, and slide the filter out carefully.
• Inspect for debris, then seat the new filter with the correct airflow orientation.

The engine filter cleans air for the 3.0L inline-6 turbos combustion, while the cabin filter cleans HVAC air for passengers.

The engine air filter protects the turbocharged intake system from dirt that can reduce power or harm the mass airflow readings. The cabin filter traps dust, pollen, and particulates before air reaches the vents, improving in-cabin comfort. Both are serviceable items, but they do different jobs and live in different locations. If you need guidance, you can schedule service online.

• Engine filter: performance and engine protection.
• Cabin filter: HVAC airflow and passenger air quality.
• Both require periodic inspection and replacement.

Typical signs include reduced power, lower fuel economy, rougher idle, weak HVAC airflow, or a musty odor.

On the GLS-Class, a dirty engine filter can make the inline-6 feel sluggish and may increase fuel consumption. A clogged cabin filter often shows up as diminished vent output or lingering odors. Visual checks help, but professional inspection ensures the airbox seals and MAF sensor stay clean. If you notice these symptoms around Lynnfield or Boston, book a visit for confirmation.
