Mitsubishi 2.0L EVO 8 Bore 3.425

Built for high-performance Mitsubishi EVO 8 engine applications, these custom forged pistons are engineered to deliver exceptional strength, reliability, and durability in demanding street and racing environments. Precision-machined from premium SM8427FT forgings, this piston set is designed for serious engine builders seeking a lightweight yet robust piston solution capable of handling elevated cylinder pressures and high RPM operation.

Featuring a 3.425" (86.995mm) bore and 3.701" (94.00mm) stroke combination, these pistons are optimized for a 2.0L Mitsubishi EVO 8 platform. Advanced piston design incorporates precision valve reliefs, optimized ring package dimensions, and a lightweight 302-gram piston weight to improve engine response while maintaining long-term durability.

To further enhance performance and wear resistance, these pistons feature an entire piston Type III (Green) anodized coating with crown coating, providing added protection against heat, friction, and harsh operating conditions.
