The stock intake is not a horrible design. It gets nice cool air and has the potential to have a little of that forced in. At the very front of the engine bay there is a plastic shroud that covers the radiator and has a large bunp in front of the intake snorkle. Either removing the shroud or cutting out the area containing the bump will allow you stock (or replacement i.e. Iceman) to get a little bit more cool air. If cut out, you may wish to cover the remaining hole (mostly for aesthetics) with tape, cardboard or a sheet of thin metal.
