Big Sucker Bevelled Air Filter Arlen Ness (manufacturer ref: 18-309) — a complete kit designed for modern classics and touring bikes that want a sleek aesthetic without sacrificing reliability. The bevelled satin black look and CNC machined aluminium construction give the engine a vintage/tech accent while remaining discreet under the cover.

• Complete kit: single-piece support plate, proprietary breather tubes, filter cover, high-performance filter, gaskets, oil reservoir, and fasteners.
• Breather management: each breather incorporates an O-ring at the cylinder head and vents through tubes into the throttle body — an advanced ventilation system designed to redirect excess oil from M8 engines back to the engine.
• Filter: pre-oiled black cotton media, reusable and washable for a good compromise between airflow and filtration.
• Design: bevelled round shape, soft radius air intake to minimise flow disruptions.
• Finish: black, suitable for Vintage/Classic and Touring environments.

Designed to integrate with modern architectures like M8 and a reliable choice for personalising a Harley without compromising the ventilation components, this Big Sucker brings style, durability, and simplified maintenance. Check model compatibility before installation.
