JE Pistons BMW S14B32 13:1 KIT Set of 4 Pistons

Forged from 2618 aluminum, these JE Pistons are built to handle the high tensile strength required for demanding performance applications. They are specifically designed for the BMW S14B32 engine, offering a 13.00:1 compression ratio with a dome piston design. This kit includes everything needed to outfit your engine with four new pistons, including high-quality wrist pins, locks, and JE Pro Seal premium piston rings, all made 100% in the USA.

JE Pistons incorporates their proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by reducing skirt width. This design, along with a shorter wrist pin, also saves additional weight. Depending on the specific application, these pistons may also feature an accumulator groove to reduce pressure from combustion gases, improving ring seal and reducing ring flutter. A skirt coating, also application-dependent, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

This piston set is engineered for optimal performance and durability, making it a solid choice for engine builds focused on power and reliability. Please note that this kit is not CARB approved and cannot be shipped to California.
