Adding thickness to the core does improve efficiency, but the gains are less and less as the core gets thicker, and the downside is that it becomes harder to get the air to pass through the core. Since the same (or lesser) volume of (cooling) air passes through the core, the air first contacts and transfers heat out of the front of the intercooler, and thus is hotter by the time it reaches the back half of the intercooler's thickness, and has less (or no) capacity to absorb out additional heat from the intercooler. It also moves more slowly through the core due to the increased thickness, compared to a 3" or 3.5" thick core.

This is not merely a thicker direct fit intercooler. we increased frontal area by 56% over stock and its ambient face is bigger than the other direct fits
so by your analogy if we increase front 1/2 thickness by 56% back half thickness should have 56% less of a heat removal job to do and become 56% more effective right? keeping the back half factory like was a design element we wanted to keep as we didn't want to lose the advantage of the factory draw through fan and shroud.
increased weight? an intercooler is a heat sink if you have a cold mass of higher weight it has more of an ability to absorb heat. keeping this mass cool can be achieved in 2 ways:
increased frontal area *check*
a draw through fan *check*
moving air through the core more slowly or quickly is one design element you play with in an intercooler design, you only have the chance to cool the charge down while its IN the core, thats why we are testing 2 different cores of varying fin geometries and releasing the best design!
