Description

The Manley Performance 632205CE-4 Platinum Series piston set is engineered for high-performance Subaru WRX and STI engines, delivering exceptional strength and durability. Crafted from domestic 2618 alloy forgings, these pistons are designed to withstand the rigors of demanding tuning applications while maintaining precise fit and function. The set features a 100mm bore size with a displacement of +.50mm, and an compression ratio of 8.5:1, making it ideal for extreme duty use.
Manley’s pistons incorporate proven cam and barrel (skirt) profiles that optimize power output while preserving cylinder wall integrity. Precision-machined ring lands and grooves ensure an excellent seal, translating into increased horsepower and improved efficiency. The unique fixturing process used during manufacturing allows for accurate skirt turning and ring groove machining in a single operation, ensuring ring-to-skirt squareness and consistency across every set.
Standard chrome moly wrist pins are included, providing high strength and reliability. For select applications, optional upgrades to 9310 and Turbo Tuff/DLC alloys are available, offering even greater durability under high stress conditions. The pistons are coated with moly skirt coatings on select part numbers, reducing friction and wear during operation. These features, combined with strict quality standards, make the Manley Platinum Series pistons a trusted choice among professional engine builders and tuners seeking performance and longevity.
