Wiseco Honda K-Series +10.5cc Dome 1.181x87.5mm Piston Shelf Stock Kit

Forged from 2618 aluminum, these Wiseco pistons are built for serious performance in Honda K-Series engines. The 2618 alloy offers improved tensile strength, making these pistons well-suited for heavy to severe duty race applications where durability under extreme stress is critical. Each piston features a +10.5cc dome and measures 87.50mm in bore diameter, designed to work with your K20A engine build.

Wiseco machines these pistons in the USA, incorporating features like precision ring grooves, anti-detonation grooves, and additional ring seal enhancements to ensure reliable performance. The crown is fully machined for accuracy, and forced pin oiling helps keep the wrist pin lubricated. A notable feature is the ArmorGlide skirt coating, which helps reduce friction, resist seizure, and contribute to quieter operation, all important factors when pushing an engine to its limits.

This shelf stock kit includes a set of four pistons, ready for your high-performance Honda K-Series build. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
