Is the "sandwich plate" that goes between the SuperCharger and inlet manifold in the Mini Blizzard kit available separately as I have another route I want to try in attempts to intercool my L67.

The mini blizzard intercooler plate assembly is available separately. This comes with both sides of the intercooler place and the heat exchanger core. To give you a clearer idea, please check out the fitting instructions in the link below:
