BMC FB873/08RACE Universal Cylindrical Race Air Filter

The BMC FB873/08RACE is a universal cylindrical Race-specification air filter engineered for maximum airflow in high-performance and motorsport applications. Part of BMC's acclaimed Race filter line, this filter is built for riders and drivers who demand more than standard filtration can offer.

BMC's Race filters share the same cylindrical form as their standard counterparts but feature a tuned filtering element specifically designed to push even greater volumes of air to the engine. By optimizing the cotton gauze layer configuration, the Race spec delivers elevated airflow well beyond what a factory paper filter can provide, making it the ideal companion for engines that have been mechanically or electronically modified for peak output.

Key Features:

• Race-tuned cotton gauze construction — multi-layered oil-soaked cotton gauze filters particles as small as 7 microns, compared to the OEM standard of 10 microns
• Enhanced airflow — reduced filtration layers versus standard BMC filters deliver maximum air volume for modified and race-prepped engines
• Epoxy-coated alloy mesh outer shell — protects the filter media from petrol fumes and oxidation caused by air humidity
• Full Moulding construction — produced from a single mould with no welded joints, eliminating weak points and ensuring long-term structural integrity
• High-durability rubber sealing — long-life rubber provides optimum adhesion characteristics across a wide range of airbox shapes
• Pre-oiled and reusable — filter arrives ready to install and can be cleaned and re-oiled using the BMC regeneration kit
• 97.5% filtration efficiency — tested to ISO 5011 standard

Important Note: BMC Race filters are intended for closed-circuit motorsport and track use. Due to the significantly increased airflow, street use is not recommended without reprogramming the engine control unit to correctly manage the air/fuel mixture. Proper ECU tuning will yield a marked increase in performance.

BMC supplies filtration solutions to elite motorsport programs in Formula 1, MotoGP, and WorldSBK, and the FB873/08RACE brings that same race-proven technology to your build.
