Every design decision — from the four-layer oiled cotton gauze to the epoxy-treated aluminium mesh surround — is validated against stringent filtration benchmarks, giving you documented confidence in what your engine breathes.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eTested to international performance and quality standards, ensuring measurable filtration efficiency and engine protection exceeding that of conventional paper filters.\u003c\/li\u003e\n\u003cli\u003eFour-layer oiled cotton gauze construction delivers an optimised pressure-drop ratio, improving airflow to the engine without sacrificing filtration integrity.\u003c\/li\u003e\n\u003cli\u003eEpoxy-treated aluminium mesh frame resists petrol vapour exposure and oxidation, protecting the filter structure over thousands of kilometres of road and track use.\u003c\/li\u003e\n\u003cli\u003eRubber-sealed perimeter frame prevents cracking and ensures an airtight, drop-in fit in the OEM airbox — no modifications required.\u003c\/li\u003e\n\u003cli\u003eWashable and reusable: properly maintained, the filter outlasts multiple paper replacements, reducing long-term running costs.\u003c\/li\u003e\n\u003cli\u003eEnhanced particulate absorption keeps abrasive debris out of the combustion chamber, safeguarding piston rings, valves and cylinder walls.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eRace Know-How in a Road-Legal Package\u003c\/h2\u003e\u003cp\u003eBMC built its reputation supplying air filtration solutions to professional motorsport programmes before channelling that expertise into its replacement filter range. The FM556\/20 inherits that lineage directly: the same multi-layer cotton gauze technology used to maximise airflow at race RPM is calibrated here for the S1000RR's street and track operating envelope. The result is a filter that passes more air than the OEM paper unit while maintaining the filtration precision your engine demands.\u003c\/p\u003e\u003ch2\u003eConstruction \u0026amp; Durability\u003c\/h2\u003e\u003cp\u003eThe filter medium consists of four precisely layered sheets of cotton gauze, each pre-treated with a specific oil formulation that captures fine particles on contact rather than relying solely on mechanical blockage. This approach allows a freer passage of air through the media whilst retaining superior dirt-holding capacity compared to a single-density paper element. The surrounding aluminium mesh is coated in an epoxy solution that neutralises the corrosive effects of fuel vapour, ensuring the structure remains rigid and dimensionally stable season after season. The moulded rubber frame completes the package, sealing cleanly against the OEM airbox seat to eliminate unfiltered air bypass.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThe BMC FM556\/20 is a direct replacement air filter designed to fit the following motorcycle:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eBMW S1000RR (K46) — model years 2009 to 2018\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eInstallation is a straightforward like-for-like swap into the standard airbox.
