Yeah, the Laminova cores and that idea have been out for a while. The cores are VERYYYY efficient, WAY more than any water air IC out right now, and have little to know pressure loss either. They are damn expensive, like $200 a piece, 4+ cores needed, and require a lot of machine work to mount, flow and run them correctly. Many pro race teams run them in where its legal, and a few production cars use the same idea. Its a cool technology.
