Feuling Parts — BA Series Air Filter (Ref. 5447)

The BA Series from Feuling offers a one-piece machined aluminium air filter that combines a sleek look with performance suitable for vintage/classic and touring builds. The sturdy cover and chrome round insert highlight the wide 2.5" red filter mounted on a one-piece cage. The elongated intake horn, precisely machined, accelerates airflow and increases intake volume for a more uniform engine filling.

• Construction: billet aluminium, one-piece design for simplified installation and a neat finish.
• Filter: washable and reusable 2.5" element with integrated cage (red).
• Intake Body: high-flow machined horn, diameter and cone optimised for balanced dynamic airflow.
• Ventilation: original configuration with cylinder head ventilation directed towards the intake and ports optimised to meet emission constraints.
• Origin: rear plate engraved MADE IN USA — developed and validated on flow bench and in road tests.
• Finish: chrome and red — ideal for a polished vintage or touring style.

Designed for demanding builds, this kit is particularly relevant for engines equipped with ported cylinder heads, enlarged intakes, and throttle bodies. Specifically fits Harley-Davidson Dyna Wide Glide, Low Rider, and Fat Bob 1690 (2017).
