Wiseco Honda F20C/F22C S2000 +7cc Dome 11:1 CR Piston Kit - Set of 4

This kit includes a set of four Wiseco pistons, designed specifically for Honda F20C and F22C engines found in the S2000. These are forged pistons, meaning they start as a block of 2618 aluminum that's heated and hammered into shape, giving them improved tensile strength over cast pistons. This process makes them well-suited for heavy to severe duty performance applications where reliability under stress is critical.

Each piston features a +7cc dome to achieve an 11:1 compression ratio, which is a notable bump over stock and can help increase power output when paired with appropriate tuning. The pistons are fully machined, including precision ring grooves, anti-detonation grooves, and features designed to improve ring seal. They also come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. For added durability, these pistons feature forced pin oiling to ensure the wrist pin stays well-lubricated under high loads.

Wiseco manufactures these pistons in the USA, focusing on custom-level performance and durability. While these pistons are built for serious racing and performance builds, please note they are not CARB approved and cannot be shipped to California. If you're rebuilding the top end of your F20C or F22C engine for demanding use, these Wiseco pistons offer a well-built option with features aimed at longevity and performance.
