Re: Cold Air Intakes
Operating without limitations, my suggestion is having something custom made, with dual oval pipes made of 3" aluminum with mandrel bends, ceramic coated flat black. Include 2 K&N cone filters mounted behind the grill, the radiator support will need to be "modded" to clear these pipes.
The iron listed in your signature tells me you have a builder and the financial backing and this will be a good start to achieve the results you seek.
