Spool Performance IFX-EA150 Upgraded DI Injectors for EA839
In our testing on a B9 S4, these injectors paired with a TTE850, we have had a customer run a 9.98 1/4 mile on street tires, full weight! No lightweight wheels with drag radials, no stripped interior, no race seat! Full OEM weight!
Unlock the full fueling potential of your EA839 platform with the Spool Performance IFX-EA150 Upgraded Direct Injectors—precision-engineered to support serious power with OEM-like refinement. Delivering 35% more flow and an additional 1,000 psi of maximum rail pressure capability, the IFX-EA150 injectors provide the fueling headroom required for high-boost, high-airflow builds.
Proper fueling headroom, at a proper price!
These fit both the EA839 3.0T and 2.9TT !!
Once boost, airflow, or ethanol content increase, the factory EA839 injectors quickly become the limiting factor. High-RPM pulse-width extensions, late injection events, and cylinder-to-cylinder imbalance can all show up when the DI system is pushed beyond its design.
The IFX-EA150 injectors eliminate these constraints by offering:
35% Increased Flow CapacityMore mass fuel per event with reduced pulse-width at high RPM.
+1,000 psi Additional Pressure CapabilityStronger atomization and improved combustion consistency even under extreme cylinder pressures.
Shorter Injection WindowMeets fueling targets earlier in the cycle for cleaner, more complete combustion.
Performance Advantages
Supports higher boost and more aggressive ignition timing
Stabilizes fueling at high RPM where stock injectors fall short
Enables safe power on ethanol blends, including E50–E85, without running the DI system at its limits
Prevents lean-out, late-cycle injection, and uneven fuel distribution
Ideal for big turbo and hybrid turbo EA839 builds
Optimized for E85 and High Ethanol Content
Ethanol requires ~30% more volume than pump gas to achieve the same energy output. This places enormous strain on the stock DI injectors and HPFP. The IFX-EA150 injectors provide the additional flow and pressure needed to run E85 or high-ethanol blends confidently and safely.
With the added flow capacity and increased pressure ceiling, the injectors maintain:
Consistent lambda under high load
Safe injector pulse-width at redline
Stable spray pattern and atomization even with ethanol’s higher volume demand
Testing done a Jackal motorsports as shown Excellent gains over RS injectors
