Arlen Ness Big Sucker performance air cleaner for Harley-Davidson Milwaukee-Eight Installation

This air cleaner kit is specially designed to pull in the most air possible under the factory air cleaner cover on a Milwaukee Eight Touring Motorcycle. The aluminum backing plate features a really cool hidden breather system and an ingenious internal catch-can, which Arlen Ness says makes sure no blow-bye oil mist touches the air filter.
