Agreed, these do matter for cooling. Dave, look around online, some of the Miata aftermarket places have the factory pieces availabe (gomiata I think?). I just put an NRG aluminum panel on my SU car becauase bling matters... (and it was the same price as the factory piece, and I don't have rules to live by)
