Wiseco Pistons KE315M84 Forged Performance Piston 84mm Bore BMW M50

The Wiseco KE315M84 is a precision-engineered forged performance piston designed for BMW M50B25 and M50B28 inline-6 engines. Manufactured from aerospace-grade aluminum using Wiseco's proprietary forging process, this piston delivers exceptional strength, reduced weight, and improved heat transfer compared to cast alternatives.

Key Features:

• 84.00mm bore diameter with -13.5cc dome volume
• Compression ratio options: 8.8:1 or 9.3:1 depending on rod length
• ArmorGlide skirt coating reduces friction and cylinder noise
• Forged construction offers superior impact and fatigue resistance
• Compatible with 140mm connecting rods (M50B25) or 135mm rods (M50B28)
• Precision CNC machining ensures exact tolerances
• Includes piston rings, wrist pin, and circlips

Wiseco pistons feature advanced metallurgy and finite element analysis to optimize strength-to-weight ratios. The ArmorGlide coating is permanently applied and lasts the life of the piston, providing consistent friction reduction and improved break-in characteristics. Ideal for performance builds, forced induction applications, and engine rebuilds requiring proven reliability.
