BA Series Air Filter – Transparent Cover by FEULING PARTS: a stylish air cleaner designed for retro and touring motorcycles. The monoblock housing offers a sleek silhouette and simplified installation compared to multi-plate constructions. The transparent acrylic cover showcases the black filter and reveals the machined aluminium of the intake horn.
Designed and developed on a flow bench, then validated through testing, this filter is aimed at riders seeking a refined aesthetic and improved engine breathing through optimised airflow — particularly suited for Vintage/Classic and Touring environments. Manufacturer reference: 5544. Compatible with many Harley-Davidson Dyna models (e.g. Wide Glide, Low Rider, Fat Bob) depending on model and year.
