Namura uses a MOS2 (Teflon/Molybdenum) coated piston skirt which is a rolled-on process that bonds 10x stronger than sprayed on coatings. This coating offers greater heat transfer and reduces friction to help to eliminate cold seizures. The head of the piston is machined smooth to reflect combustion temperatures away from the piston. Some tests have shown this feature can increase horsepower and fuel economy by up to 6% in gains.
