Big Sucker Stage I Air Filter by ARLEN NESS — manufacturer reference: 18-459

Designed for cruisers and touring bikes, the Big Sucker Stage I kit adopts Arlen Ness's design principles to provide a freer intake without sacrificing aesthetics. The black aluminium top cover, featuring integrated standoffs and a directional venturi, directs airflow for a more consistent engine breathing. The "Hidden Breather" backplate conceals the breathers: each outlet passes through an O-ring at the cylinder heads, travels through the plate, and exits inside the throttle body via proprietary tubes.

• Materials: black aluminium body, pre-oiled surgical cotton filter media, washable and reusable.
• Filtering surface: +200% compared to the original filter with a conical base for a better capture area.
• Complete kit: one-piece plate, breather tubes, performance filter, cover, gaskets, oil reservoir, and fasteners.
• Compatibility: compatible with the original OEM outer cover.

Ideal for Road Glide riders and other large custom bike enthusiasts looking for a refined, durable, and easy-to-maintain intake. Plug-and-play installation on compatible models — sleek black finish that integrates with the original lines.
