The smoothly machined piston crown reflects combustion heat, reducing carbon buildup and increasing horsepower and fuel economy by up to 6%. The anodized piston dome increases heat resistance and extends service life. ### Precision and Durability Thanks to Hypereutectic Casting The hypereutectic casting process ensures a higher silicon content in the material, which translates to reduced thermal expansion and increased wear resistance.
