Not sure about the other stuff, should have the induction kit in about a week. Not heard about the cooling box at the moment, but by the looks of it, the box will be made out of plastic.
They make them for the IS300, but I geuss I'll have to measure out sizes first before they could do any more for the 200.
Altezzascott will be the man to contact about buying them, as I don't want to get a slapped wriste :P
