The Manley Performance EJ205 Platinum Series Piston Set is engineered for high-performance Subaru WRX models from 2002 to 2005. Designed with the professional tuner in mind, these pistons feature advanced materials and precision manufacturing to deliver exceptional durability and power. Crafted from domestic 2618 alloy forgings, they offer superior strength and resistance to the stresses of high-performance engines. The pistons include cam and barrel (skirt) profiles that optimize power output while maintaining gentle contact with cylinder walls, promoting longevity and consistent performance.

A key feature of these pistons is the chrome moly wrist pins, which provide enhanced durability over standard options. For select part numbers, there are upgrade options to 9310 and Turbo Tuff/DLC alloys, further improving wear resistance in demanding applications. The unique fixturing process used during manufacturing allows for skirt turning and ring groove machining in a single operation, resulting in precise ring land and groove dimensions. This precision enhances ring seal, which translates into increased compression and power. The pistons are also equipped with moly skirt coatings on select part numbers, reducing friction and improving performance.

This piston set is designed to meet the demands of high-performance engines, with features that support reliable operation under increased boost or horsepower conditions. The set includes rings and is suitable for enthusiasts and professional engine builders seeking a trusted solution for Subaru EJ205 engines. Please note, these pistons are not carb-approved, and proper acknowledgment is required prior to installation.
