BA Series Air Filter — Clear Cover (Manufacturer Part No: 5574)

The FEULING BA Series air filter kit combines a custom look with engineering designed for the road. Its clear cover showcases the one-piece construction and the machined aluminium intake horn, while the elongated intake ducts promote accelerated airflow for a more direct engine breathing. Ideal for touring and road machines seeking a polished finish and simplified installation.

• Construction: One-piece with machined billet aluminium horn and engraved rear plate MADE IN USA / FEULING.
• Filtration: Washable and reusable element 2.5" wide, equipped with a one-piece cage for increased longevity.
• Design: Round shape, black finish with clear cover for a technical and visible style.
• Performance: Designed on a flow bench, tested on a bench and validated on track to optimise intake flow and engine response — results may vary depending on settings and modifications (cylinder heads, intakes, throttle bodies).
• Compliance: Originally configured with OEM-type cylinder head ventilation; external ventilation for racing available separately (part no. 1012-0263).

Designed for touring/road bikes (e.g. Road Glide, Street Glide Ultra CVO), this filter provides a refined look and optimised airflow for enthusiasts of performance and customisation.
