2011-2016 Ford EcoBoost 3.5L Forged FSR Pistons
The 3.5L EcoBoost engine is Ford’s flagship ecoboost engine. Capable of high loads for long durations, the oem pistons will become the weak link when pushing these vehicles to the limit and installing big turbos at high boost. JE’s solution is their high strength 2618 aluminum alloy FSR forging with meticulous CNC machining. JE’s FSR pistons are engineered for extreme applications, retaining the forged direct injection bowl with oversize valve relief and tool steel wristpins. These pistons use asymmetric skirts with 9:1 or 10:1 compression and stock bore, 25 over or 50 over.
