BMC Replacement Air Filter Suzuki GSX-R 600/750 (2011-2017) FM628/04

Built to outperform the factory paper filter in every measurable way, the BMC FM628/04 replacement air filter is engineered for Suzuki GSX-R 600 and GSX-R 750 riders who refuse to compromise on materials or long-term value. Four layers of low-viscosity oil-treated cotton gauze, encased in a protective aluminium mesh frame, deliver the kind of airflow and filtration integrity that OEM filters simply cannot match.

Key Features

• Four-layer cotton gauze construction saturated with low-viscosity oil maximises airflow while maintaining exceptional filtration efficiency across the entire rev range.
• Aluminium mesh surround shields the cotton media from petrol vapour and oxidation, dramatically extending filter service life compared to paper alternatives.
• Rubber frame perimeter eliminates the risk of cracking or distortion, ensuring a consistent, leak-free seal inside the airbox at all times.
• Higher dirt-absorption capacity keeps harmful particles away from the engine without choking airflow or introducing significant pressure drop.
• Washable and reusable design cuts long-term running costs — clean, re-oil and refit rather than buying a new filter each service.
• Validated against internationally recognised test standards, guaranteeing that performance and filtration claims are backed by independent verification.

Premium Construction

Where most stock filters rely on a single layer of pleated paper, the BMC FM628/04 stacks four layers of precision-woven cotton gauze. Each layer is evenly treated with a specially formulated low-viscosity oil that captures fine particulates without significantly impeding airflow. The result is a filter that feeds the GSX-R's engine a denser, cleaner charge of air than the OEM unit is capable of providing. The enclosing aluminium mesh is not merely decorative — it forms a rigid structural shell that resists deformation under high-velocity airflow and protects the cotton media from chemical attack by petrol vapour and atmospheric oxidation. Together with the moulded rubber perimeter frame, this construction gives the FM628/04 a working life measured in years rather than service intervals.

Performance on Road and Track

Swapping a restrictive paper filter for the BMC FM628/04 reduces intake pressure drop, allowing the GSX-R 600 and GSX-R 750 to breathe more freely at every throttle position. Riders typically notice a crisper throttle response and marginally improved mid-to-top-end pull — tangible gains that make the upgrade worthwhile whether you spend your weekends on B-roads or circuit days. Unlike single-use paper filters, the FM628/04 can be removed, cleaned with a dedicated BMC cleaning kit, re-oiled and refitted, making it the more sustainable and cost-effective choice over the life of the machine.

Fitment & Compatibility

The BMC FM628/04 is a direct OEM-replacement drop-in filter requiring no airbox modification. It fits the following models:

• Suzuki GSX-R 600 (2011-2017)
