The Mitsubishi 4B11T Piston Set by JE Pistons is a high-performance forged piston kit tailored for the 2007-2015 Mitsubishi EVO X. With a 3.465-inch bore and a -1cc dome, these pistons are crafted for enthusiasts looking to enhance their vehicle’s engine capabilities.

Incorporating over 75 years of JE Pistons' engineering expertise, this set is forged in the USA using 2618 aluminum for unmatched tensile strength—a critical factor for high-demand performance. The pistons’ proprietary Forged Side Relief (FSR) design reduces friction and power loss, offering a lightweight solution with a shorter wrist pin. Optional skirt coatings further minimize friction and operating noise, promoting longevity in tough conditions. The accumulator groove technology (where applicable) reduces combustion gas pressure, enhancing ring seal and ensuring consistent power delivery.
