Wiseco K241A100 Forged Piston Kit Honda K24 Sport Compact Series

The Wiseco K241A100 is a forged sport compact piston kit engineered for Honda and Acura K24-series engines. Built on decades of motorsport development experience spanning Formula 1, Indy Racing League, NHRA Pro Stock, MotoGP, AMA Superbike, and AMA Motocross and Supercross, Wiseco brings race-proven piston technology to performance street and competition builds. Each piston is forged and machined at Wiseco's ISO-certified facility in the USA.

Key Features:

• Generous Valve Pockets — Designed to maximize airflow around the valve head, allowing the use of oversized valves and high-lift camshafts without clearance concerns.
• Optimized Crown Profile — Piston crown geometry promotes maximum intake charge efficiency through cross-flow scavenging during intake and exhaust valve overlap, increasing the fuel-air charge for greater power output.
• Anti-Detonation Dome Design — Crown and dome geometry optimizes quench during the compression and combustion cycle, improving resistance to detonation and pre-ignition for longer engine life and higher power potential.
• Precision-Machined Ring Grooves — Calculated groove root diameters and axial widths deliver an excellent surface finish and flatness, maximizing ring seal while minimizing blow-by and oil consumption.
• Advanced Forging Technology — Manufactured at a world-class, ISO-certified forging facility using complex forged shapes, advanced alloy materials, and feature-aligned grain flow technology for superior strength-to-weight ratio.
• Complex Skirt Profiles — Engineered skirt geometry reduces power-robbing friction while maintaining bore stability for consistent ring seal throughout the RPM range.

ArmorGlide Skirt Coating

Wiseco's ArmorGlide skirt coating is developed and validated through an in-house dynamometer program. The dry-film lubricant coating minimizes friction and allows a tighter piston-to-bore fit compared to uncoated pistons, reducing piston rock and noise while improving wear resistance and overall engine longevity.

Sold as a complete kit including rings, wrist pins, and clips.
