Hmmm, educate me, please. How does the length of the intake manifold affect 
the torque and power? I can understand if there is significant variation 
between one cylinder and the next, but length?

Bends, twists, turns, all that I can understand, too. It affects flow. But 
length?

I'm at a loss on this one (and no expert, either). Anyone?
