BMC Replacement Air Filter MV Agusta F3 675/800 (2012-2026) FM712/04

Engineered with motorsport-derived expertise, the BMC replacement air filter FM712/04 is built from premium materials that set it apart from the standard paper element. The four-layer cotton gauze construction, precision aluminium mesh reinforcement and low-tack oil treatment combine to deliver superior airflow, exceptional filtration and a service life that far exceeds any disposable OEM filter — all on the MV Agusta F3 675 and F3 800 from 2012 through 2026.

Key Features

• Four-layer cotton gauze media saturated with low-tack oil ensures maximum air permeability while capturing a higher proportion of dirt and particulate than a standard paper filter.
• Aluminium mesh outer layer shields the cotton element from fuel vapour and oxidation, preserving integrity and performance across thousands of kilometres.
• Rubber frame perimeter prevents cracking and seals cleanly into the OEM airbox housing, eliminating bypass leaks.
• Washable and reusable — clean, re-oil and refit rather than replace, making the FM712/04 a cost-effective long-term investment.
• Reduced pressure drop across the filter media translates into measurable gains in throttle response and engine performance.
• Validated against internationally recognised test protocols, confirming filtration efficiency and flow rate to the standards a precision machine like the F3 demands.

Build Quality and Materials

BMC's choice of materials for the FM712/04 reflects the same philosophy that underpins their motorsport catalogue. The four-layer cotton gauze is the foundation: each layer contributes to a graduated filtration structure that traps particles progressively, preventing premature clogging while sustaining airflow under hard acceleration. The low-tack oil treatment binds fine dust without restricting flow — a balance that paper media simply cannot achieve at the same level.

The aluminium mesh that encases the cotton pack is not a cosmetic detail. It actively resists the corrosive effects of fuel vapour that can degrade lesser filter materials, and it provides the structural rigidity needed to maintain shape under the turbulent airflow conditions inside a high-revving triple. The rubber frame seals the assembly precisely against the F3 airbox, ensuring every cubic centimetre of intake air passes through the filter rather than around it.

Performance on Road and Track

Replacing the factory paper filter with the BMC FM712/04 delivers a noticeably higher volumetric airflow to the F3's engine. The reduction in pressure drop means the intake system works with less restriction, supporting cleaner combustion at all throttle positions. Whether you are exploring the upper reaches of the rev range on a circuit or threading through open roads, the filter's consistency across varying temperature and humidity conditions ensures the engine always receives the cleanest, most unrestricted charge of air available.

Fitment and Compatibility

The BMC FM712/04 is a direct replacement fitment for the following models:

• MV Agusta F3 675 — model years 2012 to 2026
• MV Agusta F3 800 — model years 2012 to 2026

The filter is a drop-in fit requiring no modifications to the airbox. No additional hardware or adapter is needed.
