Performance Air Filter for Mercedes Benz E G GLE GLS S Class (2017-2025) M177 4.0L Twin-Turbo Engine

Premium drop-in upgrade for your AMG's 4.0L twin-turbo V8. This BMC cotton gauze filter captures particles down to 7 microns while flowing better than factory paper—engineered for the M177 engine's high-output demands.

Factory Fitment, Competition-Level Filtration

Your Mercedes-AMG isn't just a luxury vehicle—it's a hand-built performance machine with a twin-turbocharged V8 that demands optimal airflow. The M177 engine under your hood produces serious power, but the factory paper filter prioritizes longevity over flow. This BMC replacement changes that equation without compromise.

Built using BMC's Full Moulding process, this filter is crafted from a single piece with zero welded joints—eliminating weak points that cause common filter failures. The multi-layered cotton gauze flows significantly better than OEM paper while capturing particles as small as 7 microns (versus 10 microns for factory filters). Better protection, better airflow, one simple upgrade.

Key Features at a Glance

• Superior Filtration: Traps contaminants down to 7 microns—30% finer than OEM paper filters
• Increased Airflow: Multi-layer cotton gauze allows maximum air volume to reach your turbos
• Full Moulding Construction: Single-piece design eliminates joints and potential failure points
• Epoxy-Coated Mesh: Alloy mesh protects against fuel vapors and moisture oxidation
• Long-Life Gasket: Durable, high-adhesion rubber ensures perfect seal in your airbox
• Washable & Reusable: Clean and re-oil with BMC regeneration kit—lasts the life of your vehicle

5-Minute Installation

This is a direct OEM replacement for your factory air filter. No modifications, no cutting, no adapters required. Simply open your airbox, remove the old paper filter, and drop this one in. Takes less than 5 minutes with zero tools. The filter arrives pre-oiled and ready to install—just fit it and drive.

Built for High-Output Turbocharged Engines

The cotton gauze material is soaked in low-viscosity oil that captures particles without restricting airflow. The epoxy-coated alloy mesh provides structural support while protecting against the harsh under-hood environment of turbocharged AMG powerplants—fuel vapors, heat cycling, and humidity. This is the same construction proven in Formula 1 and used by performance manufacturers worldwide.

Why Upgrade from Paper?

• Better Turbo Response: Improved airflow means quicker spool and sharper throttle response
• Long-Term Value: Washable design eliminates replacement filters every service interval
• Finer Filtration: Better particle capture protects your expensive turbos and engine internals
• Racing Proven: BMC filters are used by Formula 1 teams and OEM performance divisions
