Has anybody ever tried it?
A cool air intake is an intake system where the air filter is still under the hood, but blocked off in a front corner of the engine bay allowing the cool air to come into the intake.
I was wonder if it's been attempted or not? I would relocate the battery to where the filter is right now, and run the filter to where the battery is right behind the headlight. To complete the set-up you'll need to seal off the area, basicly put a piece of sheet metal with a rubber seal around the top edge, reducing heat, and sealing everything out.
I'm thinking about doing something like this.
It would look something like this:
