Big Sucker Air Filter Kit (Manufacturer's Ref: 18-320) — ARLEN NESS
The Stage I Big Sucker kit is a classic and refined intake solution designed for touring and vintage customs. The single-piece aluminium backplate incorporates a discreet breather system: each breather is equipped with a watertight O-ring at the cylinder heads and connects directly to the throttle body, forming a nearly closed circuit without the need for external hoses.
This kit combines meticulous aesthetics (chrome finishes) with a design focused on airflow, suitable for customization enthusiasts and long rides. Particularly suitable for the Harley-Davidson models listed below, as well as other customs and touring bikes equipped with the same interface.
