ARLEN NESS - Method™ Air Filter Clear Cover (Ref. 18-965)

The Method™ Clear Series by Arlen Ness combines retro style with modern technology: forged aluminium housing with black anodised finish and a transparent polycarbonate cover treated to resist engine oil and UV rays. The window allows observation of the internal movement of the intake system, while the radius air inlet ensures an unobstructed flow to the throttle. An aesthetic and functional choice for vintage/classic customs and touring bikes that want to showcase their intake.

• Construction: black anodised forged aluminium housing with hardened transparent polycarbonate cover.
• System: concealed breathers with O-rings at the cylinder head, passing through the plate and exiting inside the throttle body via proprietary tubes — no external hose required (quasi-closed system).
• Filter: pre-oiled black cotton media, reusable and washable for optimal flow and filtration.
• Supplied with: support plate, forged housing, transparent cover, filter, seals, and all necessary hardware.
• Design: round shape, black finish, transparent look for a neat visual effect on custom and touring bikes.

Installation compatible with many large twins (e.g. listed Harley-Davidson models) — check the reference before ordering. Simple maintenance: cleaning and re-oiling the media as recommended to maintain performance and longevity.
