DCD, yeah it's HKS cooler piping, but I opted to just get the rubber elbow replacement kit instead of the complete piping kit.
Matt,
in this pic just the piping and apexi super suction kit, more parts are leaving japan on tuesday once golden week finishes.
Durzel,
I got them for pretty much cost price so that made up for the long wait. All up it would work out to be around 1600 pounds give or take, for the 4 rims.
