Big Sucker Air Filter - ARLEN NESS • Manufacturer's ref: 600-303
The Big Sucker by Arlen Ness is an intake filter with a sleek design, intended for motorcycles in the Touring category. Its next-generation mounting plate and non-flat aluminium backplate are designed to promote smooth airflow to the engine. The monoblock top plate incorporates a venturi that directs air straight to the throttle body, enhancing intake consistency.
The kit includes a cover and a high-performance filter element, pre-oiled at the factory for effective filtration while allowing a good airflow rate. Designed for riders concerned about air intake and throttle response, it integrates particularly well on custom Touring bikes with a large intake diameter.
