Enhance your Subaru WRX EJ205 engine with the JE Pistons JEP314447 set, designed for optimal performance and durability in high-demand applications. Crafted from high-strength 2618 aluminum, these forged pistons are engineered to withstand the rigors of racing and spirited driving. Each piston is precisely machined and forged in the USA, ensuring consistent quality and performance. The set includes four pistons, wrist pins, locks, and JE Pro Seal premium piston rings, providing a comprehensive upgrade for your engine.
JE Pistons utilize their proprietary Forged Side Relief (FSR) forging design, which minimizes friction and power loss through reduced skirt width and a shorter wrist pin. The inverted dome/dish design helps optimize compression ratios while maintaining reliable sealing. An accumulator groove, depending on your specific application, helps reduce pressure from combustion gases, decreasing ring fluttering and improving ring seal for more consistent power output.
Additional features include a skirt coating that reduces friction and wear on piston skirts and cylinder walls, as well as operating noise. These pistons are specifically tailored for the Subaru WRX EJ205 engine with a 79mm piston diameter and a 92.5mm bore, offering an ideal balance of strength and performance. Designed for racing and high-performance street use, they are not carb-legal but are built to deliver maximum power and durability. Made entirely in the USA, this piston kit is a reliable choice for enthusiasts seeking to upgrade their engine with premium forged components that meet demanding specifications.
