In comparison to the external K/N units they appear to be a 1/3 rd of the size or less.

I'm sorry they are bigger than that. Top Secret uses HKS air filters for their intakes. I havent measured but they are either 200mm (7.87in) or they are the twin 150mm (5.9 in). Most likely with the 80mm inlet.

Its just my tiltshift photography that makes it look miniature. :P
