Arlen Ness Monster Sucker Air Cleaner for Early Harley-Davidson Twin Cam

If you want no-nonsense looks, more air than your cylinder heads can handle, and a filter that stays outta the way of your knee, you probably want a Monster Sucker.

  • Monster Sucker features hidden breather technology with more filter surface area than the Big Sucker for maximum performance
  • Patent-pending hidden breather system declutters the side of your motorcycle visually, eliminating the need for any external hoses or hardware
  • Filter features an inverted top to pull in air not only from all sides of the filter but also from the front for a mild ram-air effect
  • Filter is constructed from synthetic material that is water-resistant, which eliminates the need for a rain sock except in the most inclement of weather
  • Filters are reusable and do not require oil; just rinse and dry
    • Dry filters hinder airflow less than traditional oiled-gauze elements
  • CA-friendly—exempted under California Air Resource Board exemption D-639-12 when installed on 2001-2017 EFI models
  • Installed images are for reference only
  • 1999-2017 Harley-Davidson Big Twin except Milwaukee-Eight, any model with fairing lowers, 2008-2016 Harley-Davidson Touring and Trike, 2016-2017 Harley-Davidson Softail, 2014-2015 Harley-Davidson CVO Softail, or 2016-2017 Harley-Davidson Low Rider S
  • 109-0294; replaces 1010-2102, 81-000
