Considering the throttle body on the N62 doesn't really do anything...go for it. TB Spacer is meant to speed up air flow. Your infinitely variable length intake manifold already does that.
You could combine the intake, a larger bore throttle body, and software reprogramming to gain 8HP according Dinan. Maybe you'll feel the 2% increase in power, but you'll definitely hear a difference.
