JE Pistons BMW N54B30 84mm Bore 9.5:1 Forged Piston Kit – High-Performance Engine Replacement

Description

Upgrade your BMW N54B30 engine with the JE Pistons Part Number 338094, a premium forged piston kit designed for optimal performance and durability. Crafted from high-strength 2618 aluminum and manufactured entirely in the USA, these pistons are engineered specifically for high-demand applications, ensuring reliable power delivery whether on the street or the track. The kit includes six pistons, wrist pins, locks, and JE Pro Seal premium piston rings, providing everything needed for a complete rebuild or upgrade.
JE Pistons are renowned for their innovative design features such as Proprietary Forged Side Relief (FSR) forging, which reduces friction and minimizes power loss by optimizing skirt width and shortening the wrist pin. The pistons also feature an accumulator groove (application-dependent) that helps reduce pressure from combustion gases, improving ring seal and maintaining consistent power output. A skirt coating further reduces friction, wear, and noise, enhancing overall engine longevity and performance.
Designed with precision for specific engine applications, these pistons deliver an ideal compression ratio of 9.5:1 and a bore diameter of 84mm. Their inverted dome/dish profile is optimized for high-performance setups, making them suitable for racing, drifting, or spirited driving. As a testament to JE Pistons’ commitment to quality, these components are 100% forged and machined in the USA, ensuring the highest standards of manufacturing excellence. Whether you’re building a race engine or upgrading your daily driver, JE Pistons offer the proven performance and durability needed to push your vehicle to the next level.
