Performance Air Filter for Mercedes Benz C Class/E Class/GLC/GLK

High-Flow Filtration for Mercedes-Benz M270 & M274 Turbo Engines

Who It’s For: Engineered for Mercedes owners running the M271 and M274 turbocharged powerplants who are tired of the stock sluggishness and delayed turbo spool.

The Symptom: The factory intake system on your Mercedes is designed primarily for sound suppression (NVH) rather than efficiency. It utilizes a thick, restrictive paper element that creates significant air resistance as the turbocharger tries to pull a vacuum. This results in a noticeable "throttle lag" when you’re trying to merge into traffic or execute a quick lane change, as the engine struggles to overcome the pressure drop across the OEM filter media.

The Engineering Fix: By swapping the dense paper for a multi-layered cotton gauze treated with low-viscosity oil, we significantly reduce the resistance in the intake tract. This filter uses a "Full Moulding" process to ensure a perfect seal within the airbox, preventing "dirty air" bypass. The fluid dynamics are improved by allowing a higher volume of air to pass through the 7-micron mesh, maintaining higher air density and allowing the turbo to reach target boost pressures more rapidly.

Why Mechanics Choose This Kit

• Optimized Airflow Velocity: By reducing the pressure drop, the M274 turbocharger operates more efficiently, resulting in a more linear power delivery and improved torque in the lower RPM range.
• Precision Filtration: While OEM filters typically catch particles down to 10 microns, this system filters down to 7 microns, providing superior protection for the sensitive mass airflow sensor and internal engine components.
• Lifetime Durability: Unlike disposable paper filters that need frequent replacement, this epoxy-coated alloy mesh construction is washable and regenerable, making it the last filter this chassis will ever need.
