The BMC Racing air filter FM903/04RACE is engineered for Kawasaki ZX-10 R and ZX-10 RR riders who demand more from their engine without compromising longevity. Retaining the exact dimensions of the OEM unit for a completely hassle-free fit, it pairs a purpose-developed racing filter medium with measurably higher airflow — the foundation any serious engine or ECU tune needs to breathe freely and perform at its ceiling.

Key Features

  • Drop-in OEM replacement geometry — no airbox modifications required, installation is straightforward and reversible
  • Race-spec filter medium delivers increased airflow to support modified engines and remapped ECUs
  • High-level filtration efficiency maintained alongside elevated airflow, keeping harmful contaminants away from internal engine components
  • Distinctive yellow stripe provides instant visual identification at a glance during servicing or pre-grid checks
  • Developed using BMC's motorsport expertise, transferring proven track technology directly to your ZX-10 R/RR
  • Optimised for riders running aftermarket exhausts, fuelling modifications, or full power-up kits where OEM airflow becomes the limiting factor

Built for Performance, Designed Around the Engine

BMC's Racing filter range occupies a very specific space: it is not a washable road upgrade, nor a fabricated race airbox. It sits precisely where many ZX-10 R owners find themselves — running a tuned motor that is being strangled by a factory filter medium calibrated for emissions compliance rather than peak output. The FM903/04RACE addresses that directly. The specialised filter medium opens up the airflow curve while retaining the structural integrity and sealing properties that protect the throttle bodies and engine internals. The result is a filter that can genuinely support power gains when paired with appropriate fuelling changes, without introducing the contamination risk of a poorly sealed or insufficiently dense aftermarket alternative.

Track Pedigree, Road-Legal Practicality

BMC supplies filtration solutions to professional racing teams across multiple series, and the material technology that informs the RACE range flows directly from that environment. For the ZX-10 RR — a homologation-inspired machine already close to the limit in standard form — the FM903/04RACE offers a meaningful incremental gain as part of a wider performance package. On the ZX-10 R used for track days or sprint events, it complements ECU flashing and exhaust upgrades by removing a bottleneck that would otherwise limit the return on those investments.

Fitment & Compatibility

The BMC FM903/04RACE is a direct-fit replacement air filter for the following Kawasaki models:
