Audi EA839 Spool IFX-EA150 Upgraded DI Injectors

The Spool IFX-EA150 upgraded DI injectors for the Audi EA839 V6 add the fueling headroom that high-boost and ethanol builds need, with OEM-like manners.

Why you need it

Once boost, airflow or ethanol content go up, the factory EA839 injectors become the limit, showing up as long pulse widths at high rpm, late injection and cylinder-to-cylinder imbalance. The IFX-EA150 flows 35% more and handles 1,000 psi more rail pressure, so fuel is delivered earlier in the cycle with stronger atomization and steadier lambda under load. Ethanol needs about 30% more fuel volume than pump gas, which makes this extra flow key for E50 to E85.
