Sorry guy... mechanical engineer here... when they do car specs they go by % weight... 1lb on a 3200lb car is negligable... as far as heat transfer, yes it channels air but nothing to drastic... similar to the air deflectors under the car to cool the brakes... dont get me wrong they are designed to cool and wouldnt be there if they did nothing... but on the other hand its nothing drastic. Remember they also have to make the car look good so they can sell it.... and those intercooler vents could also be just another marketing tool

These holes are similar to the intercooler sprayers they had on the Evo 8's... I tried to measure the differences in power and temps once with and with out it and could not get any statistical difference.... I guess that may be one of the reasons the engineers got rid of it on the 9's. And it never made it back on the 10's either....

I used the these holes in favor of brake ducts:


And no, I could not tell any difference at all by using these holes for something else.

"Outside, a new front bumper fights aerodynamic lift with an available chin spoiler that increases the low-pressure zone under the nose. Two oval nostrils in the bumper help the intercooler by ramming fresh air around its input and output pipes."

But what do engineers know...

so if ur mission to make the front bumper assembly 2 lbs lighter, improve air channeling to intercooler, and keep the marketing guy happy, what do u do? thus 1lb might be so effective if ur comparing it to the rest of the car, however, if ur project was the front bumper then 1lb is not a bad reduction, don;t u think?

However your statement is true, as a individual project it could have very well been done like that... lol always thinking outside the box
