These CNC'd 6061 aluminum blocks allow you to eliminate the factory blower coolant manifold on the LT4 supercharger and feed each intercooler brick individually. The blocks convert the inlet and outlet of each brick to a 12 AN fitting allowing end users to run significantly larger lines for the system than stock. They come anodized black.
These include a small bracket intended to lower the boost control solenoid down out of the way. These also require using a regular hose on the vacuum line connection of the snout on the driver's side.
