Opened up the airway for the intake track, removed passenger flash to pass light (removeable when i want more air, replaceable when i dont), and notched top of brake cooling passage to allow more flow to the filter. Will be building a custom air intake box and electric fan/radiator shroud for the 7 here shortly. Plan on tearing the spare 13b apart shortly, cleaning it up, and then dawning my mad scientist alter ego and transforming it into a sick, twisted, spawned from the depts of hell, sewing machine. Stay tuned... i might actually get around to that this year
