GReddy catch can - what size?

[GTI-R Kid]

In my boredom i've been browsing the Takakiara site and came across the catch cans from GReddy. There are 2 types available - a 10mm and a 15mm. Now i'm assuming this is a reference to the hose size?

Can anyone tell me if my assumption is correct? And also can anyone tell me which one fits the GTI-R?

Thanks.

Its approximately a half inch hose from the rocker, go for the 15mm.
