Product Details

The Manley 621005C-1 is a high-performance forged piston designed for de-stroked Subaru EJ257 engines, featuring 100mm bore size with an 8.5:1 compression ratio and -18cc dish design. Manley pistons are machined of high strength 2618 material, providing exceptional durability for turbocharged and high-boost applications.

Key Features:

  • Forged from 2618 high strength material for maximum durability
  • Offset wrist pin design for quiet start-ups
  • 1.285" compression distance with 5.137" rod length compatibility
  • Designed for 75mm stroke de-stroked applications (2.35L displacement)
  • Pressure balance groove for improved oil control
  • Lightweight yet robust design for long service life
  • 438 grams piston weight

This is a single piston sold without rings. The Platinum Series features very strong forged alloy construction to sustain the power and stress that comes with more horsepower and more boost. Ideal for engine builders upgrading Subaru WRX STI and WRX engines for increased performance and reliability.
