JE Pistons S54B32 11:5 KIT Set of 6 Pistons for BMW M3 Z3 Z4

This set of six pistons is engineered to enhance performance in demanding applications, providing high tensile strength due to its construction from 2618 aluminum, which is forged in the USA. Each piston has been meticulously designed to optimize durability and performance specific to each engine application.

The proprietary Forged Side Relief (FSR) design minimizes friction and power loss, featuring a reduced skirt width that effectively saves weight while also accommodating a shorter wrist pin. This innovative design contributes to improved efficiency during operation.

With a specialized skirt coating (depending on application), friction and wear on the piston skirts and cylinder walls are significantly reduced, leading to a quieter operation. In addition, an accumulator groove (also application-dependent) aids in minimizing combustion gas pressure, which enhances ring sealing and diminishes ring fluttering for more consistent power output.

This product includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings, ensuring a comprehensive solution for your engine. All components are proudly made in the USA.
