JE Pistons Forged Piston Set for BMW N55B30 Engines

Unleash the performance potential of your BMW N55B30 engine with this high-quality forged piston set from JE Pistons. Engineered for power and reliability, these pistons are forged in the USA using 2618 aluminum, providing the strength needed for demanding performance applications.

Performance-Tuned Features:

  • High-Strength Forging: Made from 2618 aluminum for superior tensile strength and resistance to extreme conditions.
  • Application Specific: Designed precisely for the BMW N55B30 engine to ensure optimal fit and performance.
  • Optimized Compression: Features a 9.5:1 compression ratio, balanced for power and drivability.
  • Dish Volume: Includes a -14.7cc dish volume, carefully engineered for the N55B30 combustion chamber.
  • Precision Bore: 84mm bore ensures accurate fitment and efficient engine operation.
  • FSR Design: Utilizes the proprietary Forged Side Relief (FSR) design to minimize friction and power loss through reduced skirt width.
  • Weight Reduction: Shorter wrist pins contribute to lower reciprocating mass for improved engine response.
  • Wear Protection: Skirt coating (where applicable) reduces friction and wear on piston skirts and cylinder walls, while also lowering operating noise.
  • Complete Kit: Includes high-quality wrist pins and locks for a comprehensive installation.

Manufactured 100% in the USA, this JE Pistons set is built to the highest standards of quality and performance for your BMW.
