Monster sucker air cleaner kit with beveled black cover | ARLEN NESS

Product description

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 throttle body 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 include Arlen Ness forged billet covers

Will fit 88-90 models also; breather system is not applicable for these model years
