Message	If the throttle bodies fed the same side, the air flow would have to take a turn. With the dual intake setup, the driver side TB feeds the passenger side cylinder bank. This allows the intake runner to have a much more straigh and direct shot into the heads and ultimately the piston chamber. Im not sure if this was the original design implementation, or if this was a side effect of purposely making it a cross flow design to aid in equalizing/balancing, but either way its far superior to having the throttle body feed its same side bank of cylinders. If it did that, with out plenum desing, it would make quite a few more turns, hampering air flow.
