The forged Hyper Piston KIT is essential for turbo tuning the S660, and is the same quality as the OEM. The forged piston is made of 2618 aluminum alloy, which has excellent strength, heat resistance, and wear resistance. It is the perfect piston for tuning engines that have been supercharged with a turbo engine. Furthermore, the slipper-type ultra-lightweight piston delivers performance suited to the S660.
Recommended to use in conjunction with forged hyper connecting rods.
It is introduced on Ameblo's "M&M HONDA's Honda Honki."
