Wiseco Honda K-Series +10.5cc Dome 1.181X89.0mm Piston Shelf Stock Kit

Wiseco is known for making strong, reliable engine components for demanding applications. If you're building a high-performance K-series engine for your Honda Element, or any of the other compatible Acuras and Hondas, this piston set is built to handle serious power. These aren't your average pistons; they're forged from 2618 aluminum, which gives them improved tensile strength over cast aluminum, making them well-suited for heavy to severe duty use.

Each piston in this set features a +10.5cc dome and a 1.181-inch pin diameter, with a bore size of 89.00mm. The precision ring grooves, anti-detonation grooves, and additional ring seal features help ensure a solid seal between the piston and cylinder wall, which is crucial for performance and longevity. They also come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. The crown is fully machined, and the design includes forced pin oiling to keep the wrist pin lubricated under high stress.

This set includes four pistons, rings, and is designed for a direct fit in your K20A engine. Keep in mind these pistons are not CARB approved and cannot be shipped to California. For serious engine builds, these Wiseco pistons are a solid option to consider.
