AFI VR6 24V INTAKE MANIFOLD Tuner Headquarters

Certainly look like sturdy and quality-built pieces of "art" but at $1300 USD you'd want to make sure there were decent gains.

Its easy to find proof that the 12v VR6 heads had terrible flow design (and then they talk of increasing valve size and cam lift duration) but there isn't a lot of info on the 24v.

As far as I can determine the 24v head was designed by Cosworth. I am taking that to mean that they redesigned the 12v head and that the two heads are relatively similar aside from the obvious number of valves.
