Whether you are chasing lap times or simply want every horsepower the inline-four has to offer, this is the filter that unlocks it.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFour-layer oiled cotton gauze construction maximises airflow while maintaining filtration efficiency far above standard paper elements\u003c\/li\u003e\n\u003cli\u003eLow-tack oil treatment strikes the optimum balance between particle absorption and air permeability, reducing pressure drop to an absolute minimum\u003c\/li\u003e\n\u003cli\u003eSurrounding aluminium mesh shields the media from petrol vapours and oxidation, preserving filter performance over thousands of kilometres\u003c\/li\u003e\n\u003cli\u003eRubber frame eliminates the cracking and seal failures that plague lesser aftermarket filters under sustained high-rpm use\u003c\/li\u003e\n\u003cli\u003eWashable and reusable — a single purchase replaces the recurring cost of disposable OEM paper filters\u003c\/li\u003e\n\u003cli\u003eValidated against international test standards for filtration efficiency and flow, ensuring real-world performance matches the engineering claims\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eRacing DNA, Road-Going Durability\u003c\/h2\u003e\u003cp\u003eBMC built its reputation on the pit lanes of MotoGP and World Superbike before bringing that technology to production-based machines. The FM478\/04 is a direct result: a filter that flows more air than the factory Honda paper element without sacrificing the filtration that keeps your engine clean. On track, the gain in mid-to-top-range response is immediately noticeable; on the road, the reusable construction means the filter earns back its purchase price many times over across a season of riding.\u003c\/p\u003e\u003ch3\u003eConstruction Detail\u003c\/h3\u003e\u003cp\u003eThe four-layer cotton gauze is precision-woven to create a consistent, tortuous path for incoming air — trapping fine particles whilst allowing a far greater volume of air to reach the throttle bodies than a paper filter permits. The aluminium mesh surround is not merely structural; it forms a chemical barrier against the petrol vapour that degrades unprotected filter media, keeping the cotton layers supple and effective. The moulded rubber frame seats perfectly in the CBR 600 RR's airbox without modification, maintaining an airtight seal at all engine speeds.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThe BMC FM478\/04 is a direct OEM replacement fitment for the following:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eHonda CBR 600 RR — all variants, model years 2007 to 2025\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eNo airbox modification is required.
