BA Series Air Filter – Transparent Cover (Manufacturer Ref: 5454)

The FEULING Parts BA Series air filter kit combines style and efficiency for customs and touring bikes. Its machined aluminium monobloc body and transparent acrylic cover showcase the red cartridge, providing a polished "show" look while being designed for road use. The high-flow intake bell, outer lip, and inner cone are optimised to promote a faster and more uniform airflow to the throttle, thereby enhancing the breathing of the V-Twin.

• Construction: machined billet aluminium + transparent acrylic cover
• Filter: washable and reusable element, 2.5" wide with monobloc cage
• Design: monobloc for simplified installation and clean aesthetics
• Performance: developed on a flow bench, tested on a dyno, and validated on track — power and torque gains have been observed, particularly on engines equipped with modified heads, enlarged intakes, and throttle bodies
• Emissions: originally configured with OEM-type head ventilation directed towards the intake
• Manufacturing: Made in USA
• Finish: black + transparent + red element

Ideal for Vintage/Classic and Touring categories, this BA filter provides both a refined visual appearance and airflow management designed for large displacements, particularly modern Harley-Davidson customs.
