I remember members arguing about this.

I found this from 2009: Developed for winter commuting (but now I run 'em year around)
Frank Lee cut a sheet of cardboard and put it under his car hood and used 1" foil-faced foam in his truck.

Daox posted Super fast warm up mod - Engine insulation in 2011.

The fifth post is Frank Lee sharing his older thread.

The argument I remember is that cardboard and coroplast have negligible insulative properties.

I also remember people putting fiberglass welding blankets under their hoods, but I will need to finish that thread and possibly look elsewhere later.
