Bore, 9.00:1, Inverted Dome/Dish, 6 Cyl. Piston Kit These pistons utilize our dedicated Forged Side Relief (FSR) forging that was specifically designed to increase strength.

• Proprietary Forged Side Relief (FSR) forging design minimizes friction and power loss with reduced skirt width and saves additional weight with a shorter wrist pin
• Accumulator groove (depending on application) helps reduce pressure from combustion gases, reducing ring fluttering and improving ring seal for consistent power
• Skirt coating (depending on application) reduces friction and wear on piston skirts and cylinder walls while simultaneously reducing operating noise
• Forged in the USA using 2618 aluminum, yielding high tensile strength needed for high-demand performance applications
• Designed specifically for each engine and use application to provide optimized performance durability
• Includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings
• Made 100% in the USA

Upgrade your BMW engine with the JE Pistons BMW S52B32 US 9:1 Forged Piston Kit, designed for high-performance applications. Crafted from high-strength 2618 aluminum and manufactured entirely in the USA, these pistons offer exceptional durability and optimized power output. The proprietary Forged Side Relief (FSR) forging process reduces friction and power loss by minimizing skirt width and utilizing a shorter wrist pin, contributing to increased efficiency and performance. Each piston features an inverted dome/dish design with a 3.425-inch bore and a compression ratio of 9.00:1, tailored specifically for the S52B32 engine to deliver consistent and reliable power. The pistons also incorporate an accumulator groove, which helps reduce pressure from combustion gases, thereby improving ring seal and reducing ring flutter, resulting in more stable engine operation. Additionally, the skirt coating reduces friction and wear on piston skirts and cylinder walls, while also lowering operating noise for a quieter engine experience.
