JE Pistons Subaru EJ257 83mm Stroke Forged Piston Kit with 8.50:1 Compression Ratio

Description

Upgrade your Subaru Impreza engine with the JE Pistons SUB EJ257 83mm Stroke Forged Piston Kit. Crafted from high-quality 2618 aluminum in the USA, these pistons are engineered for durability and performance in high-demand applications. Designed specifically for the EJ Series engines, this kit includes four pistons, high-quality wrist pins, locks, and JE Pro Seal premium piston rings, ensuring a comprehensive upgrade for your engine. The forged construction and precision machining provide excellent tensile strength, ideal for both street and racing use.
JE Pistons’ proprietary Forged Side Relief (FSR) forging design minimizes friction and power loss by reducing skirt width and decreasing weight with a shorter wrist pin, enhancing engine responsiveness. The accumulator groove, depending on the application, helps reduce pressure from combustion gases, decreasing ring flutter and improving ring seal for consistent power delivery. The piston skirts feature a specialized coating that reduces friction and wear on the piston skirts and cylinder walls, which also helps lower operating noise for a smoother running engine.
These pistons are manufactured and assembled entirely in the USA, adhering to strict quality standards to ensure reliability and performance. Suitable for Subaru Impreza models from 2004 to 2007, they are an ideal choice for enthusiasts seeking improved power, efficiency, and durability. Please note that these pistons are not CARB approved and require acknowledgment of proprietary restrictions. Whether for daily driving or racing, the JE Pistons Subaru EJ257 kit delivers proven performance and longevity, making it a top choice for engine builders aiming for victory in every race or reliable street performance.
