Sure is,....
I think the main beneficiaries of internal thermal barrier coatings are turbocharged engines and very high compression race motors. They do help contain the heat inside the chambers where it does the most good: increasing thermal expansion to increase efficiency.
The side benefit is a reduction in piston (thus oil) temperatures and cylinder head temps, both of which are critical in engines with high cylinder pressures.
Another good idea is Grady's "Rubbermaid Solution". That will really reduce cylinder head temperatures which is the key to maintaining HP when the engine is hot,....
