Description

Upgrade your Subaru WRX EJ205 engine with the Manley Performance 620005C-4 Platinum Series pistons, engineered for maximum durability and performance. Crafted from high-quality 2618 alloy forgings, these pistons deliver superior strength, allowing for reliable power output even under demanding conditions. The design incorporates proven cam and barrel skirt profiles that optimize power generation while minimizing stress on cylinder walls, making them ideal for high-performance builds. Each piston features precision-machined ring lands and grooves to enhance ring seal, contributing to increased compression and overall engine efficiency. The moly skirt coatings on select part numbers reduce friction and wear, extending piston lifespan and maintaining optimal engine performance over time. Chrome Moly wrist pins are standard, with optional upgrades to 9310 and Turbo Tuff/DLC alloys on select SKUs, providing extra durability for aggressive tuning or racing applications. The unique fixturing process used during manufacturing ensures perfect ring groove to skirt squareness, guaranteeing consistent performance and ease of installation. Designed to fit 2002-2005 Subaru Impreza and 2005 Saab 9-2X models, these pistons are perfect for those seeking to build a reliable stroker engine with a 79mm bore and 92.5mm stroke, resulting in a compression ratio of 8.5:1 with a dish configuration. This set includes pistons and rings, ready to support your high-performance engine build. Note that these pistons are not carb-approved and require carb acknowledgment prior to installation. Suitable for professional engine builders and tuners, the Manley Platinum Series pistons ensure your engine delivers peak performance with enhanced durability and consistent power output.
