Spool Performance proudly presents our upgraded DI Injector solution for the Gen2 S63 platform — the IFX 350. These injectors are not only the top-performing DI injectors available for the S63 but they've also been engineered with precision to maintain the integrity of your engine's idle and low-load behaviors. They're the ideal choice for enthusiasts who are serious about power and OEM-like engine reliability maintaining full factory control through DI.
These high-spec injectors provide a substantial 40% increase in flow rate, allowing for significant performance upgrades without the need for supplemental fuel systems.

The IFX 350 will support the journey to four-digit horsepower figures in conjunction with our FX350 high-pressure pumps for the platform.
Each injector is a product of exhaustive development and testing, ensuring not only compatibility with the latest Gen2 S63 tuning platforms but also maintaining a factory-like idle and low-load behavior. This means a direct fit and enhanced performance without compromise.
