*Moly
coating is MOS2, which stands for Molybdenum Disulfide. This coating
is applied to the piston skirt. Recognizable to most people by the
black coloring, MOS2 functions as a break-in coating. This smoothens
the surface of the piston skirt during the break-in process, leaving
a perfect working area on the piston skirts. Not only that, MOS2 also
helps reduce friction after wearing in. It is essentially insurance
for effective piston skirt-to-cylinder interface.
