Why upgrade your BMW S55 HPFP?
The stock BMW S55 high-pressure fuel pump is a well-known bottleneck when tuning for more power. The Spool FX-150 increases fueling capacity by about 50%, raising the platform’s limits so you can run higher ethanol blends and support larger turbo setups with stable rail pressure.

Protect your injectors and high-pressure system with Spool’s Bosch-spec 10‑micron high-flow fuel filter. It offers outstanding filtration on the S55 without noticeable pressure drop in the low side fuel system. Highly recommended for longevity and consistent performance.
Spool Ethanol Content Monitor
Monitor in-tank ethanol content and fuel temperature with Spool’s ECA kit. Live data is delivered to the SPOOL Ethanol Content Analyzer mobile app via BLE 4.0 low energy Bluetooth. The included braided steel, nylon-core fuel lines are 100% E85 compatible, making it the ideal ethanol monitoring solution for your BMW S55.
