The Big Sucker Stage I air filter from ARLEN NESS brings a vintage/classic style while remaining firmly focused on road/touring use.

• Material & finish: natural aluminium, silver finish, single-piece construction for durability and a neat appearance.
• Ready to install: pre-oiled, compatible with OEM air filter cover; all mounting hardware and instructions are included.
