Arlen ness Big Sucker Metacarpal Reinforcement Air filterRef : ANS00689A / 10102465

The Big Sucker Air Filter Kit Metacarpal Reinforcement ARLEN NESS (Stage 1) offers a vintage look and a refined finish for touring and classic customs. Designed to fit M8 cylinder heads, this kit combines a rounded aesthetic and CNC machined aluminium "metacarpal reinforcement" with carefully studied technical elements: an O-ring at the cylinder head, proprietary breather tubes, and a ventilation system that redirects excess breather oil back to the engine.

• Kit contents: single-piece support plate, breather tubes, high-performance filter, filter cover, gaskets, oil reservoir, and necessary fasteners.
• Materials: CNC machined aluminium body and plate, black finish.
• Filter: pre-oiled black cotton, reusable and washable, soft radius air inlet for unrestricted flow.

The concealed ventilation plate technology is an evolution of the original system for a clean integration on the housings. The assembly maintains a sleek and refined appearance, suitable for Harley Davidson Softail and touring customs seeking a vintage yet technical look.

• Colour: black
• Shape: round
• Features: pre-oiled, reusable, washable
