JE Pistons BMW N55B30 84mm Bore 9.5:1 Compression Ratio -14.7 Dish FSR Piston Set of 6

Description

Enhance your BMW N55B30 engine with the JE Pistons Part Number 338096, a high-performance forged piston set designed for optimal durability and power. Crafted from 2618 aluminum in the USA, these pistons feature a proprietary Forged Side Relief (FSR) forging design that minimizes friction and power loss by reducing skirt width and saving weight with shorter wrist pins. This innovative design contributes to improved efficiency and responsiveness in high-demand applications. The set includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings, ensuring a complete and reliable upgrade for your engine.
The pistons incorporate an inverted dome/dish design with a 9.5:1 compression ratio, suitable for a wide range of performance builds and racing scenarios. An accumulator groove (application-dependent) helps reduce pressure from combustion gases, decreasing ring fluttering and maintaining consistent power output. Additionally, the skirt coating reduces friction and wear on piston skirts and cylinder walls, while also lowering operating noise, contributing to smoother engine operation.
These pistons are specifically engineered for each engine and use application, providing an optimized balance of performance and durability. Manufactured entirely in the USA using high tensile strength material, they are built to withstand high-stress environments such as drifting, track racing, or drag racing. The set is not CARB approved but complies with other regulatory standards. Designed for serious enthusiasts and professionals, these JE Pistons are a proven choice for victory on the race track and reliable daily driving alike.
