Spool Stage 3 LPFP | BMW B48

The Spool Performance Stage 3 LPFP is a drop-in low-pressure fuel pump (LPFP) upgrade for BMW B48 engines. This solution is designed to eliminate low-pressure side limitations, especially at high power levels and when using E85 fuel.

As high-pressure fuel pumps (HPFP) become more efficient, the low-pressure fuel pump often becomes the system's bottleneck. The Stage 3 LPFP solves this with a dual pump design.

• Drop-in installation solution
• Dual pump system
• Second pump activates based on boost pressure
• Nearly 2x flow compared to stock
• Supports over 1000 whp low-pressure capacity
• Works with all fuels, including E85

Operating Principle

• Primary pump operates normally under light load
• Secondary pump activates as boost increases
• Provides additional fuel under high loads
• Ensures consistent supply to the HPFP system

Why is an upgrade necessary?

The B48 engine's stock LPFP can limit performance:

• E85 significantly increases fuel demand
• High power levels require more fuel
• HPFP does not operate optimally without sufficient supply

Stage 3 LPFP:

• Removes the low-pressure side bottleneck
• Improves system reliability
• Enables high power levels

Compatibility

BMW models equipped with the B48 engine, incl.:

• F30 LCI 320i / 320iX / 330i / 330iX
• F31 LCI 320i / 320iX / 330i / 330iX
