5150 AutoSport Pro-Xtreme Forged Pistons for BMW S63/S63TU Engines

Upgrade your BMW S63/S63TU engine—found in the F10 M5, F11/F12 M6, and E7X X5M/X6M models—with 5150 AutoSport’s Pro-Xtreme Forged Pistons, made in collaboration with CP-Carrillo. These pistons are built to handle extreme horsepower, intense RPMs, and the high cylinder pressures of turbocharged engines, making them ideal for demanding applications like drag racing, track builds, and high-performance street setups.

These pistons are suitable for use in engine blocks with factory alusil bores, no sleeving is required. Recommended piston-to-wall clearance is ~0.0025 – 0.0035 in.

Performance and Engineering Excellence

• Offset wrist pin design minimizes friction and piston noise while optimizing the rod-to-crank angle for smoother performance. Learn more about offset wrist pin design here.
• Designed to withstand up to 2000 horsepower for high-boost and turbo builds.
• Rated for 9500 RPM to maximize engine output and reliability in high-RPM scenarios.
• Engineered with advanced CAD and FEA technology for precision manufacturing and durability.

Each piston is constructed from high-strength, aircraft-grade forged steel, ensuring exceptional strength and thermal stability under high engine loads. The offset wrist pin design also requires precise installation, with the etched arrow on the dome pointing toward the major thrust side of the piston.
