A theoretical insulation on all surfaces that doesn't exist, at least not yet.
I did put a ceramic thermal barrier on the tops of my pistons and in the combustion chamber and in the exhaust ports on the Bug. But then I had a hard time getting the engine temps up to where they needed to be. Even after bypassing the oil cooler I still would hardly see oil temps above 150 °F IIRC (they never would get to 180 °F).
