Monster Sucker kit features the patented Big Sucker "hidden breather" technology. Breathers are o-ringed at the cylinder heads and exits out to the mouth of the throttle body or carburetor to provide efficient engine breathing, eliminating the need for any external hoses or hardware. Filters feature a built in inverted top to pull in air not only from all sides of the filter but also the front, which results in more performance gaining airflow. Filters are 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. Ness Monster Sucker air cleaners can be used with or without cover. The accessory rain sock can only be used without a filter cover.
