So I went to add ducting to my 05Rs today and discovered something. The 05's have the pump for the ACD on the drivers side duct. There is basically no room to add the duct. You can kinda squeeze a 3" hose in, but not really.

 

if you get a cwest pumper you can use duct nozzles from any place that sells brake ducting stuff, search brake duct on google... you'll come up with some sites... if not try naca duct.

anyway... after you obtain the duct nozzle funnel whatever you call them things, you can attatch them to the small slits under the main ducts on the cwest bumper.

this is of course an elaborate idea of something that you can apply in general fashion, you can just take duct nozzle things and stuff them under the car where you'll get direct air flow... and find a way to attach them... not the safest as tehy might fly off or you might hit something but it'll work. front fascia is not the only solution.
