Before installing the Steeda airbox, it must be assembled. The billet velocity stack is bolted on, as are two brackets and a supplied dowel pin. Then Steve swapped on the rubber mounting pin from the factory airbox and snapped the cold-air feed tube into place. Before installing the airbox assembly, you must first install the provided plastic plugs over these battery lugs. There is clearance between the metal filter shield and the lugs, but it’s always better to be safe than sorry.
