<VV> CORSA and Air Cleaner Finish is it chrome or black?

[rbuckridge at comcast.net]

Seeing all the posts on turbo air cleaner finish, chrome or black, I am surprised that CORSA or some CORSA car show judge hasn't addressed this concern. 

But then again I assume, CORSA has a set of standards to judge cars as to original equipment, fit and finish. How do they class cars at National Conventions if there is no set of standards?
