Monster Sucker kit features our patented Big Sucker “hidden breather” technology and more filter surface area for maximum performance

Hidden breathers are O-ringed at the heads and exit out the mouth of the injector/carb to provide efficient engine breathing, eliminating the need for any external hoses or hardware

Filter features a built-in inverted top to pull in air not only from all sides of the filter but also from the front, which results in more performance-gaining airflow

Each filter is constructed from synthetic material that is water-resistant, which in most cases eliminates the need for a rain sock

Filters are re-usable and do not require oil; just rinse and re-use

Kits do not include Arlen Ness forged billet covers; must be purchased separately

Cover styles available in Deep Cut, 10-Gauge or Beveled

Forged billet covers can be added at any time to any Monster Sucker kits that were originally purchased without covers (sold separately)
