Arlen Ness - Big Sucker Bevelled Air Filter Kit (ref. 50-841)
The Big Sucker Stage I kit by Arlen Ness replaces the original intake with a CNC-machined aluminium backplate featuring a bevelled design, aimed at optimising airflow to the throttle body. Its design incorporates hidden breather technology: each breather is equipped with an O-ring on the cylinder head side and vents inside the throttle body, creating a nearly closed circuit without additional hoses.
Clear installation: all hardware and instructions are included. Designed for Twin Cam Delphi EFI engines ('01-'17) and Twin Cam CV carburettor ('99-'06). Ideal for custom and touring enthusiasts seeking a robust, aesthetic, and performance-oriented intake piece, with a glossy black finish that highlights the vintage spirit of Dyna and other customs.
