Upgrade your motorcycle's performance with the industry-leading Stage 1 Big Sucker™ performance intake. Specifically engineered for Milwaukee-Eight™ models, this kit is designed to provide maximum airflow while maintaining a sleek profile by accepting your factory air cleaner cover. Featuring a one-piece aluminum backing plate with patented hidden breather technology, this system eliminates the need for external hoses or hardware for a clean, professional look.

  • New patent-pending hidden breather backing plate technology provides efficient engine breathing by directing air through proprietary tubes into the mouth of the throttle body.
  • Advanced breathing system eliminates common oil issues by directing excess breather oil back into the engine rather than onto the filter.
  • Integrated patent-pending oil reservoir can be serviced alongside your filter element to ensure no oil saturates the filter or restricts airflow.
  • Aluminum filter top plate features integrated mounting studs and a directional air venturi for increased durability and performance.
  • Performance filter is constructed from four layers of red pre-oiled surgical grade cotton, offering over 200% more surface area than the factory filter.
  • Washable and reusable filter design features a tapered bottom to maximize surface area within the factory cover.
  • Radius air inlet provides unobstructed airflow for maximum engine performance.
  • Complete kit includes a one-piece backing plate, breather tubes, performance filter, filter top, gaskets, oil reservoir, and all necessary mounting hardware.
