Read abou a guy on the net who ran several 2 or 3 inc intakes into a Dodd spirit turbo. He claims 2 large pipes by the airdam were the most efficient, any more did not make a difference.
My thought. Get a 6 inch PVC pipe. Cut in half. Mount to front of car under bumper facing forward like a snowplow. Will act like a airdam. On the ends have them blocked, drill a 4 inch hole and duct both 4 inch hoses into the airbox.
