OK here are the pictures of the air intake holster things. I think all they really do is support your intake tubes, but they are smaller than the black intake tubes, so I figure to hell with them, who wants that restriction!
There is also a little flapper door underneath, which has me confused as to what it really does. The only thing I can think of is that it let's high-speed air enter the engine compartment. Probably for cooling and warm-up purposes, but now there is a larger entryway for more air flow to come in through the grill so I'm guessing it's better cooling.

As you can see the horizontal distance is only about 32cm. Yet I might be creating some airflow drag at the intake entrace due to the fact that the intake tubes don't have a clean radius to allow for proper air flow down the pipe, near the leading edge of the intake tube. Might have to spin some alluminum insert with a correct radius for the airflow to enter smoothly.
