The Airsep system is simple to install with standard handtools. The installation took us about three hours to complete. When used with the stock airbox, the kit comes with everything you need to create a closed-loop system out of your Cummins crankcase vent tube. The system replaces your factory intake hose with a specially molded plastic tube (left), which allows for the additional space required by the filter element. The filter itself is a canister with two connection ports-one for suction and another for drainage.
