MINI has long been a source of big fun in a small package. The latest models prove that decades old mantra still holds true. JE’s line of MINI pistons are substantially stronger than OEM castings and bring the strength of 2618 aluminum to the table. They are designed for increased boost pressure, RPM, and horsepower and are the perfect complement to any performance engine build for street or competition. Each piston set includes carbon steel wrist pins, premium carbon steel gas nitrided pistons rings, and locks. Each piston is designed, forged, and precision CNC machined 100% in-house in the USA.
