Wiseco Honda K-Series +10.5cc Dome 1.181X88.0mm Piston Shelf Stock Kit

Wiseco is well-known for making strong, reliable internal engine components, especially for performance applications. This Professional Series piston kit is built for serious racers and builders who demand top-tier performance and durability from their K-series engines. These aren't your average pistons; they're designed and built to handle the stress of heavy to severe duty race builds, helping you push your engine's limits.

Each piston in this set is forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength under high stress. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal, which is crucial for consistent power and engine health. The fully machined crown also contributes to precise combustion chamber volume. For added protection and reduced friction, these pistons feature an ArmorGlide skirt coating that helps prevent seizure, lowers friction, and results in quieter operation. The forced pin oiling design ensures the wrist pin receives adequate lubrication, further enhancing durability.

This kit includes four pistons, each with a +10.5cc dome volume and an 88.00 mm bore. They are designed for the Honda K20A engine and feature a 30.00 mm compression height and a 0.8661 inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California. They are intended for sport compact applications and are a solid option for anyone rebuilding or modifying their K-series engine for demanding performance use.
