JE Pistons BMW S50B32 Euro Kit 87mm Bore -5.2cc Dome 0.827in Pin Diameter - Set of 6 Pistons

JE Pistons has been a leader in forged racing pistons for over 75 years, applying their experience to a wide range of applications. This piston set is specifically made for the BMW S50B32 Euro engine, offering a durable and high-performance upgrade. Each piston is engineered and machined in the USA using 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines operating under demanding conditions.

This kit features JE Pistons' proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width and using a shorter wrist pin for added weight savings. Depending on the specific application, these pistons may also include an accumulator groove to reduce combustion gas pressure, preventing ring flutter and improving ring seal for consistent power delivery. A skirt coating, also application-dependent, further reduces friction and wear on the piston skirts and cylinder walls, while also helping to quiet operating noise. This set includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings, ensuring you have the essential components for a complete rebuild.

This piston set is designed for optimal performance and durability in the S50B32 Euro engine. Please note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
