BMC Racing Air Filter BMW S1000RR K46 (2009-2018) FM556/20RACE

The BMC Racing air filter FM556/20RACE is a straightforward, cost-effective upgrade for any BMW S1000RR K46 owner looking to extract more from their engine without overhauling the airbox. It slots in as a direct replacement for the OEM filter, so you get an immediate improvement in airflow the moment the airbox lid goes back on.

Key Features

• Increased airflow through BMC's specially developed Race-grade filter media, improving throttle response and top-end power without sacrificing filtration quality.
• Drop-in fitment — identical dimensions to the standard BMW air filter, meaning no modifications to the airbox or mounting points are required.
• Optimised for modified engines — designed specifically for S1000RR owners who have remapped the ECU or added performance parts and need the airflow to match.
• Excellent engine protection maintained alongside the higher flow rate, guarding against harmful contaminants even under hard use.
• Instantly recognisable yellow stripe identifies the filter at a glance during servicing — a practical touch that keeps maintenance simple.
• Race-proven BMC filter construction, trusted by performance riders and professional teams across circuit and road applications.

Race Technology for Real-World Riders

BMC's Race filter range occupies a practical middle ground: the elevated airflow rating suits riders running ECU remaps, aftermarket exhausts or other performance modifications, yet the filter is equally at home on a fast road bike that simply deserves better than a stock paper element. The filter media is engineered to flow more air per square centimetre than the standard unit while retaining the multi-layered filtration that keeps abrasive particles away from the cylinder head. The result is a usable, day-to-day upgrade that pays dividends on both the commute and the circuit approach roads.

Installation & Servicing

Because the FM556/20RACE mirrors the geometry of the original BMW filter exactly, installation is a straightforward service-interval swap. No adapter plates, no trimming, no specialist tools — open the airbox, remove the old filter, drop in the BMC unit and close up. BMC Racing filters are also cleanable and re-oilable, making the long-term running cost significantly lower than repeatedly replacing disposable OEM paper elements.
