Some additional features of Namura pistons include:
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
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.
Hypereutectic Casting Process
Provides higher silicon content for reduced expansion rates and additional wear resistance; it also has an ability to withstand higher cylinder temperatures.
