This is version 2.0
Yeah, I know what it looks like
The idea is to help the air make the 90 degree turn towards the heads and than again 90 degrees so that the air flows alongside the heads and air comes from the front (again, like original) and from above.
With this form I hope the air stays laminar and the heads that need more air get it in this way.
Also hope that overall cooling is better now the heads are more favoured for cooling
