I don't know what they are bragging about here. A plastic-fiberglass manifold? It should have been made of CF. The 6.3L AMG V8 has a magnesium manifold, that's something to write home about.

- From front to rear, the entire flow of intake air in the new eight-cylinder power unit does not require the usual hot-film air mass flow meter with its obligatory sensors. Instead of determining engine load by means of such elaborate sensors, therefore, which would also create disadvantages in air guidance due to the geometry of the components involved, the V8 power unit of the new BMW M3 uses the engine control unit to perform this function
That means Alpha-N is likely used. Which means, tuning air intake would be difficult.
