Namura pistons are direct OEM replacements with a few key advantages. First is the Teflon/Molybdenum coating on the skirts to increase heat transfer, reduce friction and reduces scuffing and seizures. Machined smooth heads and anodized domes increase durability and can even add horsepower and fuel economy. Lastly, the Hypereutectic casting process provides a higher silicon content for reduced expansion rates and additional wear resistance. Namura pistons are simply the best value on the market. All the advantages of a top of the line piston at a great price!
