the first proposed step would be to just remove the black plastic air dam just above the ac condenser.

air entering the grills is slowed down and forced to flow through the radiator, the consenser, and into the inlet by this air dam and by the seals along the sides of the radiator. by removing the upper air dam, some of this air may flow over the top of the consenser and right onto the ic snouts and by the bottom of the ic ( and onto a hai, if you have one.. )

if somebody is set up to measure engine and ic temps., this might be pretty easily tested.

if the engine didn't overheat because of less flow through the radiator, the ic efficiency improved, and too much junk wasn't blown into the engine bay, this flow path could be made more sophisticated by making a horizontal splitter that ran from the top of the condenser (or radiator) forward and down to the grill, thus ceating a dedicated "upper" flow path.

if that worked, aft facing louvers about halfway back on the hood could help vent this path to a higher velocity/lower pressure area.

if the grill area isn't made larger, this won't add drag to the car, since the air entering the grills pretty much comes to a stop anyway. making the grill larger is an option, but will add drag.

i've never been enthusiastic about the whole mcs front end/ic/inlet flow path. i understand that what's there functions well enough and is the best compromise for general production. but for people wanting to use the air more efficiently at the price of crud in the engine bay, i think there are things to be done with this air path.( need a smiley here for thinking..... )
