Monster Sucker Air Filter Kit — ARLEN NESS (ref. 81-001)

Designed for custom and touring enthusiasts, the Monster Sucker kit from Arlen Ness features a vintage-chrome styled breather and an enlarged filter surface to optimise engine breathing without heavy modifications. The system incorporates Big Sucker "hidden breather" technology: concealed breathers equipped with O-rings at the cylinder heads and the injector/carburettor outlet, eliminating the need for hoses or additional accessories.

• Design: conical aluminium breather with chrome finish, sleek look for custom and touring.
• Filtration: hydrophobic synthetic media, washable and reusable — no oil required, a simple rinse is sufficient.
• Airflow: integrated inverted top to capture air from the sides and front, enhancing airflow to the intake.
• Durability: water-resistant and suitable for daily use on long roads.

Notes: the kit does not include the Arlen Ness cover (sold separately). Compatible with Cam Delphi EFI and Twin Cam CV (models 1999–2006). Not suitable for motorcycles equipped with a lower fairing. Ideal for adding character and improved breathing to your custom/touring.
