BA Race Series Air Cleaner Kit - Raw - Red Filter
The Feuling Parts BA Race Series (RS) air cleaner kit, part number 5421, is engineered for optimal performance on Harley-Davidson motorcycles, particularly those with modified or ported engines. Originally designed for our 130 Bagger GP race engine, this air cleaner features a compact height that is just under one inch taller than standard models, providing an impressive 33% increase in filter surface area. This expanded filter capacity delivers higher airflow and improved filtration efficiency, translating into notable horsepower and torque gains across a wide range of engine configurations. Its design enhances engine breathing, lengthening intake runners and increasing air velocity for a balanced and dynamic airflow, which supports better throttle response and overall engine performance.
