- Professional installation is recommended when the component affects engine operation, suspension geometry, braking, fuel delivery, or other safety-critical systems.
- Original catalog note: Features: Billet Piston Kit Bore: D: 87.5mm / 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 and contributes to weight reduction. - Three oil jets deliver cooling oil precisely for effective cooling. - Nickel plating above the top ring groove improves knock resistance and wear resistance. - A two-layer coating enhances anti-seizure properties and reduces friction. - Original shortening pi
Fitment and specifications can vary by HKS part number, model year, trim, transmission, drivetrain, and market. Confirm the SKU and application before ordering, particularly on modified vehicles.
