its not all about the volume of air, the runner lengths are long and P&P from the factory.
OK... I think I get you. The IM can handle more flow than the stock tubing and filter provide. Certainly an good case for intake modification if I've ever seen one.
What about the heads? Can they handle more air than the stock intake can provide as well? Generally that's where you hit a wall when it comes to NA engines... if the heads flow less CFM than the IM or intake tubes then modifying the intake won't do you any good anyways.
