Arlen Ness Monster Sucker 90 Degree Air Intake:
- Monster Sucker kit features a 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
