Manley Performance
Manley Platinum Series Forged Piston Set - Subaru WRX/STI 2004+ (EH257) 99.75mm Bore 8.5:1
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2004 and newer Subaru WRX and STI models (EH257).
The Manley Platinum Series forged piston set is engineered for high-performance Subaru builds requiring exceptional strength and precision. Constructed from domestic 2618 aluminum alloy forgings, these pistons are designed to withstand the extreme cylinder pressures of turbocharged applications while maintaining optimal weight and durability.
- 2618 Alloy Forgings: High-strength domestic alloy provides the structural integrity needed for high-boost forced induction.
- Precision Fixturing: Unique machining process allows for skirt turning and ring groove machining in a single operation, ensuring ultimate ring groove to skirt squareness.
- Enhanced Ring Seal: Adherence to strict tolerances for piston ring lands and grooves results in superior ring seal and increased power.
- Optimized Skirt Profiles: Specific cam and barrel profiles generate substantial power while minimizing wear on cylinder walls.
- Included Hardware: Set comes standard with premium Chrome Moly wrist pins for reliable performance.
- Key Specifications: 99.75mm bore (+.25mm oversize), 8.5:1 compression ratio, dish piston design.
- Manufacturer Part Number: 632202C-4
