BMC Racing Air Filter Honda CBR 600 RR (2007-2025) FM478/04RACE

Built on the same manufacturing principles that supply BMC filters to top-tier racing teams, the FM478/04RACE is a direct-fit race air filter for the Honda CBR 600 RR covering every model year from 2007 through 2025. Its specially engineered filter medium delivers a measurably higher airflow rate than the OEM unit while maintaining full filtration integrity — making it the natural choice for any CBR 600 RR running ECU remaps, aftermarket exhausts or other engine modifications that demand more from the intake side.

Key Features

• Race-grade filter medium engineered for significantly increased airflow without any compromise to filtration efficiency, keeping harmful contaminants away from precision engine internals.
• Identical external geometry to the original Honda air filter — drops straight into the stock airbox with no cutting, drilling or bracket modification required.
• Purpose-developed for modified CBR 600 RR engines: when paired with ECU tuning or a free-flowing exhaust, this filter allows the engine to breathe freely enough to realise its full power potential.
• Distinctive yellow stripe identification makes the filter immediately recognisable as a BMC Racing unit and confirms correct fitment at a glance during servicing.
• Reusable and cleanable construction, reducing long-term running costs compared with disposable OEM paper elements.
• Derived directly from BMC's motorsport programme — the same filtration technology trusted on the race track, packaged for real-world road and track use.

Engineering & Build Quality

BMC constructs the FM478/04RACE from a multi-layer cotton gauze medium, oiled and pleated to maximise the surface area available for filtration. The gauze layers are bonded between precision-formed polyurethane frames that replicate the OEM filter's exact profile. This attention to dimensional accuracy means the filter seats correctly in the airbox without air bypassing around the edges — a failure mode that can occur with poorly made aftermarket filters. The result is a unit that feels as solid as the Honda original but flows considerably more air under the high-demand conditions that a track session or a heavily tuned engine produces.

Performance & Road or Track Use

The FM478/04RACE is specifically intended for Honda CBR 600 RR owners who are not satisfied with stock output and are either already running or planning to run engine modifications. In a standard, unmodified engine the gains will be modest; the filter's value becomes most apparent once the ECU is remapped or the exhaust system is upgraded, because the intake is then no longer the restricting element in the breathing cycle. For track-day regulars and club racers, this filter provides the reliable high-airflow foundation that consistent lap-time improvement depends upon.

Fitment & Compatibility

The BMC FM478/04RACE is a confirmed direct fitment for the Honda CBR 600 RR across all variants produced from 2007 to 2025. No other vehicle fitment is claimed; always verify your model year before ordering.
