MOS2 (made with Teflon/Molybdenum) Coated Skirts - A rolled on application process provides a fits 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 - Reflects combustion heat and reduces 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 - Increases heat resistance and durability; pistons with anodized domes are 75% stronger than non-anodized pistons
