Manley Performance
Manley Platinum Series 100.5mm (+.5mm) 8.5:1 Dish Piston Set with Rings for 2004-2012 Subaru WRX STI (EJ257) 612005C-4
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2004-2012 Subaru Impreza WRX STI (EJ257) including Limited and Special Edition models.
Engineered for high-output EJ257 builds, the Manley Platinum Series piston set is designed to handle the increased cylinder pressures of performance turbocharged applications. These 100.5mm (+.5mm overbore) pistons are forged from domestic 2618 aluminum alloy for maximum structural integrity. Manley utilizes a unique fixturing process that machines the skirt and ring grooves in a single operation, ensuring perfect squareness for superior ring seal and longevity.
- Forged 2618 Alloy: High-strength material specifically selected for high-boost performance and durability.
- Optimized Profiles: Precision-machined cam and barrel skirt profiles reduce friction and minimize cylinder wall wear.
- Superior Ring Seal: Strict adherence to ring land and groove tolerances results in enhanced compression and more power.
- Premium Hardware: Includes high-quality Chrome Moly wrist pins and a complete high-performance piston ring set.
- Manufacturer Part Number: 612005C-4
