JE Pistons 2017+ GEN 1 Ecoboost 3.642In Bore 10:1 CR Pistons - Set of 6

JE Pistons has been a leader in forged racing pistons for over 75 years, building a reputation for durable, high-performance engine components. This set of pistons is specifically engineered for the 2017 and newer GEN 1 Ecoboost engines, featuring a 3.642-inch bore and a 10:1 compression ratio. They are designed to handle the demands of high-performance applications, whether you're on the track or pushing your vehicle's limits.

Forged in the USA from 2618 aluminum, these pistons offer the high tensile strength needed for demanding use. They incorporate JE Pistons' proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width and using a shorter wrist pin, also saving weight. Depending on the specific application, these pistons may also include an accumulator groove to reduce combustion gas pressure, preventing ring flutter and improving ring seal for consistent power. A skirt coating, also application-dependent, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

This set includes six pistons, along with high-quality wrist pins, locks, and JE Pro Seal premium piston rings. They are designed specifically for the Ecoboost engine to provide an optimized combination of performance and durability. Please note that these pistons are not CARB approved and cannot be shipped to California.
