Spool Performance IFX-EA150 Upgraded DI Injectors for EA839 - SP-IFX150-EA839

The Spool Performance IFX-EA150 Upgraded Direct Injectors are engineered to unlock the full fueling potential of vehicles equipped with the EA839 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 necessary for aggressive tuning, ethanol blends, and big-turbo applications.

Factory EA839 injectors can become a limiting factor when increasing boost, airflow, or ethanol content. Issues such as high-RPM pulse-width extensions, late injection events, and cylinder-to-cylinder imbalance may occur when the direct injection system is pushed beyond its stock design. The IFX-EA150 injectors eliminate these constraints by delivering increased flow, higher pressure, and optimized spray patterns, ensuring consistent fueling under extreme conditions.

Key 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 – Enhances atomization and combustion consistency under high cylinder pressures.
• Shorter Injection Window – Achieves fueling targets earlier in the cycle for cleaner, more complete combustion.

The IFX-EA150 supports higher boost levels, more aggressive ignition timing, and stable fueling at high RPMs where stock injectors fall short. They enable safe use of ethanol blends, including E50–E85, without exceeding the limits of the DI system. These injectors are ideal for big turbo, hybrid turbo, and high-ethanol EA839 builds, providing consistent lambda, safe injector pulse widths at redline, and stable spray patterns even with ethanol’s higher volumetric demand.

When paired with a Spool Performance FX-350 high-pressure fuel pump, the IFX-EA150 injectors provide full E85 fueling capability for high-power EA839 platforms.

Spool Performance provides full tuner support and calibration guidance, ensuring your injectors integrate seamlessly with your ECU and performance setup.
