HKS 21003-AT010 Piston Kit Step 3 (d-88) for TOYOTA GR Yaris / GR Corolla (G16E-GTS Engine)

Piston

• Diameter：D-88
• Weight：314g

Features

• Crown shaped structure speeds up the combustion spread, suppresses knocking and achieves a high compression ratio.
• A2618 material has high-temperature strength making it possible to make the wall thinner, resulting in weight reduction.
• Precise machining has eliminated excess material, achieving weight reduction.
• Bridge structure has increased structural rigidity and achieved weight reduction.
• The cooling oil from the three oil jets is efficiently guided through the piston to optimal locations, ensuring effective cooling.
• The area above the top ring groove has been nickel-plated to improve knock resistance and wear resistance.
• The use of a two-layer coating has improved for seizure resistance and lower friction.
• The weight of the port has been reduced by shortening the piston pin.
• The top ring has been titanium-coated to improve durability.
• The edges that are prone to becoming heat spots have been carefully removed by machining.
