Ceramic Crown Coating
 
This coating reflects heat into the combustion chamber and away from the piston crown, while lowering piston temperatures for increased part life. The engine can experience improved combustion and performance as a result of heat being reflected back into the fuel charge.
 
Moly Skirt Coating
 
The application of molybdenum to the piston skirt, used to reduce friction between the piston and the cylinder during engine operation. It also helps during cold start ups and high temperature operation where a substandard oil barrier on the cylinder wall could exist.
