JE Pistons ECOBOOST V6 3.5 9:1 Set of 6 Pistons

When you're rebuilding the top end of your EcoBoost V6 3.5L engine for serious performance, the pistons are a critical component. This set of six forged pistons from JE Pistons is designed to handle the demands of high-output applications, offering a significant upgrade over stock components. They are built with a 9:1 compression ratio, suitable for boosted engines where precise control over combustion is key.

JE Pistons uses a proprietary forging design called FSR (Forged Side Relief) which helps reduce friction and weight by using a narrower skirt and a shorter wrist pin. These pistons are forged in the USA from 2618 aluminum, a material known for its high tensile strength, making them well-suited for the stresses of performance engines. Depending on the specific application, these pistons may also feature an accumulator groove to help manage combustion gas pressure, improving ring seal and consistent power delivery. A skirt coating, if included for your application, further reduces friction and wear on the cylinder walls, contributing to quieter operation and longer life.

This kit comes complete with high-quality wrist pins, locks, and JE Pro Seal premium piston rings, ensuring you have the essential components for installation. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
