Specifically designed for roadsters and Sportsters, the Big Sucker Stage I by Arlen Ness offers a filtration/air intake system with a sleek design and high-quality materials. Its one-piece aluminium backplate incorporates the breather and ensures a robust attachment, while the rounded air intake minimizes clogging areas for smoother engine breathing.

• Filter element: pre-oiled round filter, washable, made of four layers of surgical-grade cotton for meticulous filtration.
• Breather system: concealed breather with O-rings at the cylinder heads and injector/carburettor outlet — no additional hoses or materials required.
• Design: Stage I, round shape, suitable for Arlen Ness® Stage I round covers.
• Supplied with: all mounting hardware and installation instructions.

Installation and compatibility: compatible with Arlen Ness Stage I round covers. Also suitable for certain older models ('88-'90) but the integrated breather system is not applicable for these years.
