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.

• CNC-machined aluminium backplate, glossy black finish
• High-performance round filter, handmade (USA) — 4 layers of surgical-grade cotton
• Pre-oiled, washable and reusable filter
• “Radius” air inlet for unobstructed airflow
• Compatible with OEM air filter cover and water-resistant
• Bevelled design for a vintage/classic look suitable for touring

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.
