Arlen ness Big Sucker Stage I Air filterRef : ANS00521A / 10102083

The ARLEN NESS Big Sucker Stage I Air Filter Kit is designed for cruisers and touring bikes that want a clean, robust, and easy-to-maintain intake. This Stage I setup combines a one-piece backing plate and a "Hidden Breather" rear plate that conceals the breathers: each breather is sealed with an O-ring and routed to the throttle body via proprietary tubes for a clean and discreet evaporation circuit.

• Increased filter surface area: over 200% more surface compared to the original filter, thanks to a conical base providing a large filtration area.
• Media: red surgical cotton, pre-oiled, washable, and reusable — simple and sustainable maintenance.
• Construction: aluminium top cover with integrated standoffs and directional venturi for a smooth and unclogged airflow.
• Finish: silver chrome, Stage I design, compatible with OEM outer cover.
• Kit contents: one-piece backing plate, breather tubes, performance filter, filter cover, gaskets, oil reservoir, and fasteners.

Installation suitable for large cruisers (Road Glide and similar). A robust part designed for a neat look while facilitating maintenance. Manufacturer reference: 18-458 — ARLEN NESS brand.
