NAMURA NA-40019-4 Piston Kit

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
