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

Engineered for high-performance applications, this piston set is crafted from 2618 aluminum, delivering exceptional tensile strength essential for demanding conditions. Each piston is specifically designed to optimize durability and performance tailored to the engine's requirements.

The proprietary Forged Side Relief (FSR) design effectively reduces friction and power loss by minimizing skirt width, while the shorter wrist pin contributes to overall weight savings. This finely-tuned design enhances efficiency and responsiveness during operation.

The included skirt coating, depending on the application, plays a crucial role in lowering friction and wear between the piston skirts and cylinder walls, thus contributing to quieter engine operation. Additionally, the accumulator groove helps alleviate combustion gas pressure, diminishing ring fluttering and ensuring a consistent seal for reliable power delivery.

Each set includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings, all manufactured entirely in the USA to maintain the highest quality standards.
