Spool Performance Spool FX-350 Upgraded High Pressure Fuel Pump System | KIA STINGER

Spool FX-350 Upgraded High-Pressure Fuel Pump System | Kia Stinger 3.3T

The Spool Performance FX-350 is a next-generation high-pressure fuel pump system designed for the Kia Stinger 3.3T. Engineered as a major upgrade over the FX-200, the FX-350 delivers higher fuel pressure, increased flow, and improved efficiency—unlocking the fueling headroom needed for serious performance.

Enhanced Pressure & Flow

• Delivers fuel at 35 MPa, dramatically increasing injector throughput
• Flow capacity improved by up to 40%, allowing injectors to reach higher boost and RPM levels without hitting injection window limits
• Ideal for larger turbochargers, higher boost pressures, and ethanol blends (E30–E85)

Improved Fuel Atomization

• High rail pressure ensures finer fuel atomization for more complete combustion
• Enhances power output, combustion stability, and cleaner operation under high load
• Optimized for direct-injection engines like the Kia Stinger 3.3T

Why Upgrade?

The stock high-pressure fuel pump becomes a bottleneck as power rises. The FX-350 delivers:

• Up to 90% more effective fueling capacity
• Supports larger turbochargers and higher boost levels
• Enables safe air-fuel ratios with ethanol blends
• Reliable performance at high RPM and load

This upgrade is essential for any serious power build.
