Performance Air Filter for Mercedes C, E, ML, GL, GLK, S-Class V6 CDI (2005-2014)

Unlocking the OM642: High-Flow BMC Performance Intake Filtration Kit

Who It’s For: Engineered for Mercedes-Benz owners running the legendary OM642 3.0L V6 Turbo Diesel powerplant who demand better efficiency, improved turbo spool, and a lifetime filtration solution.

The Symptom: The factory intake system on the OM642 engine is designed for whisper-quiet operation and long-interval neglect, utilizing thick, restrictive paper filters. These OEM filters create a significant pressure drop across the intake tract, forcing the turbocharger to work harder to pull air through the dense cellulose fibers.

As these paper filters accumulate debris, your Mercedes begins to feel sluggish during highway passing maneuvers, and throttle response becomes "mushy" as the engine struggles to satisfy its volumetric efficiency requirements.

The Engineering Fix: This BMC Performance Kit replaces the restrictive factory paper elements with a high-flow, multi-layered cotton gauze system. By utilizing a low-viscosity oil saturation and an epoxy-coated alloy mesh, we decrease the filtration threshold to 7 microns while simultaneously increasing the total airflow volume.

The result is a reduction in intake resistance that allows the turbocharger to reach target boost pressures faster, providing a sharper throttle snap and more consistent torque delivery across the entire RPM range.

Why Mechanics Choose This Kit

• Enhanced Volumetric Efficiency: By allowing the OM642 to breathe easier, you reduce the pumping losses of the engine, which is critical for maintaining peak performance in heavy chassis like the GL and R-Class.
• Full-Moulding Technology: Unlike cheaper aftermarket filters, BMC uses a single-mould construction process that eliminates welded joints, ensuring the filter frame will never crack or leak under the high-vibration environment of a V6 diesel.
• Washable & Sustainable: This is a "forever" filter. Using the BMC regeneration kit, you can wash, re-oil, and reinstall the filter, maintaining factory-fresh flow rates for the life of the vehicle.
