Like our S85 plenum we have made the throttle body adapters and velocity stacks bolt into each other so that there is zero risk of failure like the majority of plenums out there of which many have failed and the entire piece becomes scrap.

We are just debating about the lid design at the moment. Otherwise it's finished."

Sounds like more Infinity Design goodness is coming our way, but we don't know when exactly.
Wow. That’s one way to scare potential buyers away from buying other brands of CF plenums. If making claims that the majority of other brands of CF plenums on the market have had velocity stack failures is posted to the forum then supporting images and/or references to failures needs to be included. Also, if velocity stack failures are so widespread then where are all of the threads on the forum supporting his claims? This is the first time I’ve heard of this. There have been other types of failures but velocity stacks? No two CF plenums use the same velocity stack mounting scheme yet all have failed
