Wiseco Honda K-Series +10.5cc Dome 1.181x86.0mm Single Piston

When you're building a high-performance Honda K-series engine, you need pistons that can handle the stress. This single forged piston from Wiseco is built for demanding applications, designed to replace your stock piston in K20A engines with an 86.00 mm bore. It features a +10.5cc dome to help achieve your desired compression ratio.

Wiseco crafts these pistons from 2618 aluminum, a well-known material for its improved tensile strength, making it a solid choice for performance builds. The piston crown is fully machined, and it includes precision ring grooves, an anti-detonation groove, and other features to improve ring seal. For added durability and smoother operation, it's coated with ArmorGlide on the skirt, which helps reduce friction and noise while resisting seizure. The design also includes forced pin oiling to keep the wrist pin lubricated under high loads.

This piston is sold individually, so be sure to order the correct quantity for your engine. Please note that this part is not CARB approved and cannot be shipped to California.
