Spool Stage 3 LPFP | BMW S63 / S63TU (F10 / F06 / F12 / F13)

The Spool Performance Stage 3 LPFP is a high-performance Low-Pressure Fuel Pump (LPFP) upgrade for BMW S63 and S63TU engines. This solution is designed to eliminate low-pressure side limitations, especially in high-power applications and with E85 fuel.

Why is an upgrade necessary?

While High-Pressure Fuel Pumps (HPFP) can support higher power levels, the low-pressure side fuel pump often becomes the bottleneck in the system:

• Stock LPFP is insufficient for high power levels
• E85 significantly increases fuel demand
• HPFP does not operate optimally without adequate supply

The Stage 3 LPFP solves this problem:

• Nearly 2x flow compared to stock
• Supports over 1200 whp low-pressure side capacity
• Works with all fuels, including E85

Operating Principle

• A secondary fuel pump is added to the system
• The pump is boost-activated
• Forms a dual pump solution
• Ensures a consistent and sufficient supply for the HPFP system

Package Contents

• Secondary fuel pump assembly
• Activation wiring harness for the auxiliary pump
• Hobbs switch (boost-activated activation)
• Fuel lines, clamps, and installation hardware

Compatibility

Models equipped with BMW S63 / S63TU engine:

• F10 M5 (sedan)
• F06 M6 Gran Coupé
• F12 M6 Convertible (also LCI)
• F13 M6 Coupé (also LCI)
