I think on a stock 3.2 this would have only minor benefits, but on an engine moving more air, it may be beneficial. You also pick up what looks like 2" or more of runner length, which should help lower rpm torque.
I'm no expert but this is apparently something jake does on his motors.

Thanks yes I believe you are correct, good luck getting this under the Cayman cover. I am pretty sure I remember Jake indicating that these 2.7/3.2 plenums (left and right intake runners) were not even adequate for the 2.7. If I find the post...I will link it.
He didn't offer any further explanation
