The Sonoramic Commando Intake?

It's physics. They tuned the length of the runners so at certain rpm as the intake valve of one cylinder closed, creating a pulse wave, it would then travel up its length of runner, into the plenum, and push air and fuel down another runner as that intake valve opened.

Another way to put it is that they tuned the pulses in the intakes so when the pulse arrived at the valve, it was just opening, creating a ram effect to fill the cylinder.
