A18493 Big Sucker Stg Ii Std Plain Flh T99 01

For riders who need maximum airflow, the Arlen Ness Big Sucker Stage II kit steps things up with a filter element that is 20% larger than the standard Stage I version. This kit fits Touring models and provides a significant boost in intake volume for high-performance engines. The kit features the legendary Ness backing plate with integrated breather tunnels and a radiused intake manifold to ensure smooth, unobstructed air delivery. Because of the increased filter size, these kits require a dedicated Stage II air filter cover to accommodate the larger element. By eliminating external oil hoses and fittings, this system provides a clean, professional look while effectively reducing crankcase pressure. It is a proven performance solution for those pushing their Touring bike to the next level.
