BA Series Air Filter - Solid Cover by FEULING PARTS (Manufacturer's ref: 5573). Designed for cruisers and touring bikes, this compact billet aluminium kit optimises engine breathing through elongated intake ducts and a high-capacity machined bellmouth. The monoblock construction provides a clean look and simplified installation compared to traditional multi-stack assemblies.

• Material: machined billet aluminium, black finish
• Shape: round, solid cover for a neat style
• Filtering element: washable and reusable high-performance 2.5" filter with monoblock cage
• Design: optimised intake bellmouth (diameter, outer lip, inner cone) for dynamic airflow and additional volume
• Finish: engraved backplate MADE IN USA and FEULING
• Emissions: originally configured with OEM-type cylinder head ventilation directed towards the intake; external ventilation for racing available as a separate part (ref. 1012-0263)

Designed and developed on a flow bench, tested on the bench and validated on the track, this filter aims to improve airflow and engine response. Power and torque gains have been measured, particularly on engines equipped with enlarged cylinder heads, intakes, and throttle bodies. Product suitable for Touring/CVO builds; check references and compatibilities before installation.
