ARLEN NESS Monster Air Cleaner - Black 81-039

ARLEN NESS Monster Air Cleaner Black 81-039

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, Forged billet covers can be added at any time to any Monster Sucker kits that were originally purchased without covers (sold separately), Each filter is constructed from synthetic material that is water-resistant, which in most cases eliminates the need for a rain sock, Kits do not include Arlen Ness forged billet covers; must be purchased separately, Filters are re-usable and do not require oil; just rinse and re-use
