A few pics of the sleeves cast into the housing to hold the intercooler cores.

What was weird to me was that the inlet-side slots were 15mm, while the exit-side slots were all choked down to 8-10mm. I’m sure the Eaton or GM guys had their reasons for doing it this way, but Laminova specifically calls for 15mm inlet & outlet, so that’s what I opened everything up to.
