Features:

*Skirt for Ultimate Performance!!!
*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.
