JE Pistons Ford EcoBoost Pistons
JE Pistons Ford EcoBoost pistons are replacements forged using 2618 aluminum and yielding the high tensile strength needed for high-demand performance applications. They are designed specifically for your Ford's engine and use application; each piston features a proprietary Forged Side Relief (FSR) that minimizes friction and power loss with a reduced skirt width and saves additional weight with a shorter wrist pin. The pistons include high-quality wrist pins, locks, and feature accumulator grooves that help reduce pressure from combustion gases, reducing ring flutter and improving ring seal.
JE Pistons has applied over 75 years of experience to its wide range of premium forged pistons for European, import, and sport compact applications, and they have been performance-proven in victory lane time and time again. Equip your engine with the best in forged pistons—JE Pistons.
