BMC Replacement Air Filter BMW S1000RR K67 (2019-2026) FM01064

Engineered from four layers of purpose-woven cotton gauze and finished with an aluminium mesh outer shell, the BMC FM01064 replacement air filter brings genuinely premium construction to every ride on the BMW S1000RR K67. Where a standard paper element is a consumable, this is a precision component built to outlast the motorcycle — washable, reusable, and calibrated to free the engine's breathing.

Key Features

• Four-layer cotton gauze media impregnated with a low-tack oil delivers a measurably higher airflow rate than the OEM paper filter, improving throttle response and overall engine performance.
• Aluminium mesh outer shell acts as a physical barrier against petrol vapour and oxidation, extending the service life of the filter media.
• Rubber frame construction eliminates the risk of cracking or distortion, ensuring a consistent, airtight seal within the airbox at all times.
• Washable and reusable design reduces long-term running costs — clean, re-oil and refit rather than replace.
• Enhanced dirt absorption capacity keeps the engine intake cleaner for longer without the airflow restriction associated with paper elements.
• Tested to internationally recognised standards, BMC's quality control process verifies both filtration efficiency and flow performance.

Build Quality and Materials

BMC has refined its multi-layer cotton gauze technology over decades of motorsport involvement, and the FM01064 reflects that heritage. The four-ply cotton construction is the heart of the filter: each layer is oiled with a compound chosen specifically for low tack, which maintains the cotton's open weave structure and prevents the clogging that limits a paper element's useful life. The aluminium mesh is not merely decorative — it provides structural rigidity while defending the cotton from the chemically aggressive environment inside a high-performance airbox, where petrol vapour and heat can degrade inferior materials rapidly.

The rubber surround is moulded to match the exact geometry of the S1000RR K67 airbox. It seats firmly without adhesive or additional sealing, and unlike rigid frames it absorbs vibration without cracking across high-mileage road use or sustained track sessions.

Performance and Efficiency

A direct swap for the factory air filter, the FM01064 requires no mapping changes or additional modifications to deliver its benefit. The combination of improved airflow and minimal pressure drop means the BMW inline-four can draw in the volume of air its fuel injection system expects while shedding the flow restriction built into the OEM paper element. Riders typically notice sharper throttle response in the mid-range and a cleaner power delivery at higher revs. Because the filter media is maintained rather than replaced at each service interval, the airflow characteristics remain consistent over the filter's lifetime rather than deteriorating as a paper element would.

Fitment and Compatibility

The BMC FM01064 is a direct OEM-replacement air filter designed specifically for the following motorcycle:

• BMW S1000RR (chassis code K67) — model years 2019 to 2026

The filter installs in place of the standard paper element with no modifications required. Always check your chassis code before ordering to confirm fitment.
