Unlock the full potential of your Gen2 B46/B48 engine with Spool Performance’s Stage 1 IFX350 Upgraded Direct Injection (DI) Injectors. These high-performance injectors are designed to provide a 30% increase in fuel flow compared to stock injectors, ensuring your engine can handle more fuel under high load and high RPM conditions.
