Heheheh.

I suppose it is fine and it will look better all smooth and etched or powder coated.
I wouldn't mind doing a before and after dyno of it to see what happens with it. The large common plenum seems irrelevant for on boost operation and of course for offboost operation I think it would be less than optimal. I imagine they did the design as simple as possible with something that would cover all the lower intake holes.
