Performance Air Filter for Mini R55-R61 One D / Cooper D / SD Diesel (2010-2016)

High-Flow BMC Filtration for the Mini II N47 Diesel Platform

Who It’s For: Engineered for Mini Cooper owners running the N47 family of diesel engines (1.6L and 2.0L) who want to improve turbocharger efficiency and engine longevity without modifying the factory airbox.

The Symptom: The factory air intake on the N47 diesel engine relies on a thick, corrugated paper filter designed for cost-effectiveness rather than performance. These OEM filters create significant air resistance, forcing your turbocharger to work harder to draw in the volume of oxygen required for optimal combustion. Over time, as that paper becomes saturated with particulates, you’ll notice a drop in fuel economy and a sluggishness in the mid-range torque curve where these diesels should thrive.

The Engineering Fix: This BMC replacement filter utilizes a multi-layered cotton gauze system, soaked in low-viscosity oil and reinforced by an epoxy-coated alloy mesh. By switching from paper to high-flow cotton, we reduce the pressure drop across the filter element. This allows for a more consistent air density entering the compressor housing, resulting in faster turbo spool-up and better thermal management.

The "Full Moulding" construction means the filter is cast as a single piece, eliminating weak points and ensuring a perfect seal against the airbox walls to prevent "dirty air" bypass.

Why Mechanics Choose This Kit

• Superior Filtration: While OEM filters stop at 10 microns, BMC’s multi-layer cotton traps impurities as small as 7 microns, protecting your turbo’s compressor wheel from micro-pitting.
• Structural Integrity: The rubber used in this filter is designed for optimum adhesion to the airbox, ensuring that engine vibration doesn’t break the seal or cause the frame to crack over time.
• Sustainable Performance: Unlike paper filters that are thrown away, this unit is fully washable and rechargeable, meaning it’s the last filter your Mini will ever need.
