BMC Replacement Air Filter Honda CBR 1000 RR (2008-2016) FM527/04

Built to internationally validated test standards and drawing directly on BMC's motorsport programme, the FM527/04 replacement air filter is a proven upgrade for Honda CBR 1000 RR riders seeking both certified filtration performance and long-term reliability. Where the OEM paper element compromises airflow in exchange for convenience, this four-layer cotton-gauze design filters more thoroughly while letting the engine breathe freely — a combination that translates to sharper throttle response and a cleaner combustion chamber across the full rev range from 2008 through to 2016.

Key Features

• Validated to international test protocols, giving you confidence in filtration efficiency that OEM paper filters cannot match on paper or on track.
• Four-layer cotton-gauze construction, pre-oiled with a low-viscosity fluid, provides an optimal balance of airflow and particle capture — more air in, more contaminants trapped.
• Aluminium mesh outer layer shields the filter medium against fuel vapour and oxidation, preserving structural integrity and filtration performance over thousands of kilometres.
• Rubber frame surround eliminates the risk of cracking or frame distortion, ensuring an airtight seat within the airbox at all times.
• Washable and reusable — clean, re-oil and refit rather than replace, making the FM527/04 a cost-effective long-term solution.
• Higher airflow volume compared to the standard paper filter reduces pressure drop, supporting improved engine output with minimal restriction.

Racetrack Technology for the Road

BMC's filter technology originated on the race circuit, where filtration failure is not an option and every pascal of pressure drop costs lap time. The FM527/04 carries that engineering philosophy into everyday road and occasional track use on the CBR 1000 RR. The four-layer cotton medium is precision-wound and uniformly oiled to create a consistent filtration surface, while the rigid aluminium mesh prevents deformation under high-velocity airflow conditions. The result is a filter that performs at the same high standard on a Sunday trackday as it does on a daily commute.

Build Quality and Service Life

Every material choice in the FM527/04 is made with longevity in mind. The aluminium mesh resists the corrosive effects of fuel vapour that degrade lesser filter housings over time. The rubber frame maintains a reliable seal in the airbox, removing any risk of unfiltered air bypassing the medium and reaching the throttle bodies. When the filter eventually requires servicing, a standard BMC cleaning kit restores it to as-new condition — no disposal, no replacement cost, no waste.

Fitment and Compatibility

The BMC FM527/04 is a direct OEM-replacement filter, engineered as a precise drop-in fit for the following model:

• Honda CBR 1000 RR — model years 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015 and 2016

No modification to the airbox or fuel injection mapping is required for fitment. The filter seats directly in place of the original paper element.
