• 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 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 include Arlen Ness forged billet covers
