I found this air box today - I have not seen it before.
(about 3/4 of the way down the page)
It has been specifically made for S30Z's - with a recess for the shock tower - see pics:
They also show a dyno test result for it, but I can't really understand it.
Price is $570 - which appears to include pre-drilled holes to mount DCOE's.
Has anybody here bought one or seen one in the flesh?
