Features the patented Big Sucker™ hidden breather technology. Each hidden breather is o-ringed at the heads and exits at the mouth of the injector/ carb to provide efficient engine breathing and a virtually closed loop system. This eliminates the need for any external hoses or hardware
Radius air inlet provides maximum performance by providing unobstructed airflow
Aluminum breather hardware includes specially designed breather bolts and covers for clean mounting

To ensure no oil saturates the filter and restricts your airflow, Arlen Ness also integrated a new patent-pending oil catch that can be serviced when you service the filter element.
