FEATURES

POINT-1: PISTON KIT

• Replacing the gasket enables both NA and turbo-charged engine users to use this kit.
• In order to cope with the demands of high outputs, strength analysis and tests have allowed optimisation of compression ratio for flexibility of setup and high boost use.
• Piston crown had 3D design in consideration of stock direct injection system.
