MOS2 (Teflon/Molybdenum) Coated Skirts. A rolled-on application process provides a bond that is 10 times stronger than other spray-on coatings. Benefits include increased heat transfer, reduced friction, and helping to eliminate cold seizures

Machined Smooth Heads reflect combustion heat and reduce carbon buildup, protecting the top of the piston. Some tests have shown this feature can increase horsepower and fuel economy by up to 6%

Anodized Domes increase heat resistance and durability; pistons with anodized domes are 75% stronger than non-anodized pistons

Hypereutectic Casting Process provides higher silicon content for reduced expansion rates and additional wear resistance; it also has the ability to withstand higher cylinder temperatures
