Billet Piston Kit Bore: d-87.5 / Weight: 352g To enhance knock resistance and achieve higher compression ration, we have adopted HKS's unique "Triple Tumble" crown structure. (Triple Tumble crown structure) The piston crown's design creates a third tumble flow on the intake side as the piston moves upward. This quickly spreads the flame near the edge of the intake side, which helps prevent engine knock. High-temperature-resistant A2618 material and precision machining combine to deliver significant weight. "Bridge Concept Design" (BCD) structure enhances structural rigidity
