Description

Piston is anodized plus ceramic coated dome, with MOS2 coated skirts.

Ceramic and anodized coatings on piston crown both offer benefits

 

Ceramic coatings primarily act as a thermal barrier, reflecting heat back into the combustion chamber, potentially increasing efficiency and reducing piston temperatures. 

Anodizing, on the other hand, creates a hard, wear-resistant layer, particularlyuseful for protecting ring grooves and reducing friction.
