Spool Performance IFX-EA150 Upgraded DI Injectors for EA825 - SP-IFX150-EA825

The Spool Performance IFX-EA150 Upgraded Direct Injectors are engineered to unlock the full fueling potential of vehicles equipped with the EA825 engine platform. Designed for high-boost, high-airflow builds, these injectors deliver 35% more flow and an additional 1,000 psi of maximum rail pressure capability, providing the fueling headroom required for aggressive tuning, ethanol blends, and big-turbo applications.

Factory EA825 injectors can quickly become a limiting factor when boost, airflow, or ethanol content is increased. Symptoms such as high-RPM pulse-width extensions, late injection events, and cylinder-to-cylinder fueling imbalance may appear when the direct injection system is pushed beyond its stock design. The IFX-EA150 injectors eliminate these constraints by providing increased flow, higher pressure, and optimized spray patterns, ensuring reliable fueling under extreme conditions.

Key performance advantages include:

• 35% Increased Flow Capacity – Delivers more fuel per injection event with reduced pulse width at high RPM.

• +1,000 psi Additional Pressure Capability – Stronger atomization and improved combustion consistency even under extreme cylinder pressures.

• Shorter Injection Window – Meets fueling targets earlier in the cycle for cleaner, more complete combustion.

The IFX-EA150 supports higher boost, more aggressive ignition timing, and stable fueling at high RPMs where stock injectors fall short. They enable safe operation on ethanol blends, including E50–E85, without exceeding the limits of the DI system. These injectors are ideal for big turbo and hybrid turbo EA825 builds targeting 800–1000+ whp, providing consistent lambda, safe injector pulse widths at redline, and stable spray patterns even with ethanol’s higher volumetric demand.

When paired with the Spool Performance FX-350 High-Pressure Fuel Pump, the IFX-EA150 injectors provide a complete DI-only fueling solution, supporting full E85 capability and simplifying high-power builds without requiring port injection. This pairing ensures OEM-like reliability with extreme fueling capacity and a clean, emissions-friendly configuration.

Spool Performance provides full tuner support and calibration guidance, ensuring seamless integration and optimal performance.

Why Upgrade

Factory EA825 injectors are a bottleneck in high-power builds, especially on ethanol blends or large-turbo applications. The Spool Performance IFX-EA150 injectors provide higher flow, increased pressure, and optimized atomization, enabling your EA825 engine to reach its full potential safely and reliably. When combined with the FX-350 HPFP, this creates the strongest DI-only fueling strategy available, supporting extreme power levels without the complexity of supplemental fueling.
