The cost of the product will have to be determined as which is cheaper to produce and still be reliably reproduced and perform without failure. This is something Phunk will have to determine once he gets his prototypes built.

Reliability is the concern. Cracking or flanges busting off the plenum. If your lucky, the engine just screams to redline and bangs off the limiter rapid fire until you turn it off. Another scenario is a piece of it runs down into a cylinder and effectively destroys the engine.
Cosworth stopping making their CF plenums for their DE intake manifold....
