Description
Spool Performance IFX-EA150 Upgraded Direct Injectors for EA825
Unlock the full fueling potential of your EA825 platform with the Spool Performance IFX-EA150 Upgraded Direct Injectors. Designed for high-boost, high-airflow builds, these injectors deliver 35% more flow and +1,000 psi maximum rail pressure, giving your DI system the headroom needed for extreme power levels.
The stock EA825 injectors can quickly become a limiting factor under higher boost, airflow, or ethanol content, causing late injection events, cylinder imbalance, and lean conditions at high RPM. The IFX-EA150 injectors eliminate these limitations, providing:
Key Features
- 35% Increased Flow Capacity: More fuel per pulse, reducing pulse-width at high RPM for precise combustion.
- +1,000 psi Additional Pressure Capability: Stronger atomization, consistent combustion, and improved cylinder-to-cylinder balance.
- Shorter Injection Window: Fueling targets met earlier in the cycle for cleaner, more complete combustion.
- High-RPM Stability: Prevents lean-out and late-cycle injection events, even under extreme boost.
- Ethanol-Ready: Supports E50–E85 safely, providing ~30% more volume than pump gas without overloading the DI system.
Performance Advantages
- Enables higher boost and aggressive ignition timing
- Ideal for big turbo or hybrid turbo EA825 builds targeting 800–1,000+ whp
- Maintains safe injector pulse-width at redline
- Optimized spray pattern for consistent combustion with high-ethanol fuels
Perfect Pairing: Spool FX350 High-Pressure Fuel Pump
Combine the IFX-EA150 injectors with the Spool FX350 HPFP for a complete DI-only fueling solution:
- Massive DI headroom for high-boost, ethanol-heavy setups
- Full E85 support without port injection
- Cleaner combustion with shorter injection durations
- OEM-like reliability with extreme fueling capacity
- Simplified, emissions-friendly DI-only configuration
This pairing is the strongest, most reliable fueling strategy available for EA825 builds aiming for maximum power without supplemental fueling complexity.
Tuner Support
Spool Performance provides full calibration assistance, working directly with tuners worldwide to ensure your injectors perform as engineered—OEM-like reliability with extreme performance.
