Unless you are in a state that does a visual inspection when you have to have it smogged the answer is no. In fact it is a good idea to take them off the air cleaner and run them in to a catch can. Those hoses are the reason that the 3.0 will hydro-lock if it is laying on its side for a while after a flop. The oil runs up into the valve covers, into the hose, into the aircleaner and is sucked into the engine when you try to start it.
