Performance Air Filter for Mercedes Benz A Class CLA A 160 A 180 A 200 A 220 A 250 Engines

Optimized Airflow for the Mercedes-Benz M270 Engine Platform

Who It’s For: Engineered for Mercedes-Benz owners running the M270.910 and M270.920 turbocharged powerplants who are tired of the sluggish throttle response found in the stock configuration.

The Symptom: The factory intake on the M270 engine is designed primarily for silence and cost-efficiency, not peak performance. It utilizes a dense, restrictive paper filter that creates significant air resistance as the turbocharger tries to pull volume. This restriction causes a noticeable delay in boost threshold and can make your CLA or A-Class feel breathless during heavy acceleration or highway merging. Over time, these paper filters clog, further increasing the vacuum effect in the intake tract and forcing the engine to work harder just to breathe.

The Engineering Fix: This BMC performance filter replaces the restrictive factory paper with a multi-layered cotton gauze media soaked in low-viscosity oil. By using a "Full Moulding" system, the filter is created from a single mould with no welded joints, ensuring a perfect seal within the OEM airbox. This design allows for a significantly higher air-to-filter surface ratio, trapping impurities as small as 7 microns while straightening the airflow path. The result is increased air density entering the turbocharger, leading to sharper throttle snap and a more efficient combustion cycle.

Why Mechanics Choose This Kit

• Enhanced Volumetric Efficiency: By reducing the pressure drop across the intake, the M270 turbocharger reaches target boost levels with less effort, improving torque delivery across the RPM range.
• Superior Filtration Technology: Unlike the standard 10-micron paper filters, this cotton gauze system traps particles down to 7 microns, providing better protection for the sensitive internals of your engine.
• Italian Engineering: Built using an epoxy-coated alloy mesh to prevent oxidation from humidity and fuel fumes, ensuring the filter structure remains rigid under high-velocity airflow.
