Spool Performance proudly presents the pinnacle of injector technology for the S58 platform — the IFX 350. These injectors are not only the top-performing DI injectors available for the S58 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 maintainging full factory control through DI.
These high-spec injectors provide a substantial 30% increase in flow rate, allowing for significant performance upgrades without the need for supplemental fuel systems. The IFX 350's advanced design allows for consistent fuel delivery at pressures up to 390 bar. It translates into superior fuel atomization and efficient combustion, crucial for maintaining smooth operations at high power outputs. This level of performance is particularly beneficial for those looking to explore the limits of their engine's power, supporting the journey to four-digit horsepower figures in conjunction with our FX350 high-pressure pump.
Each injector is a product of exhaustive development and testing, ensuring not only compatibility with the latest Gen2 B58 tuning platforms but also maintaining a factory-like idle and low-load behavior. For drivers of G80, G82, G87, M3, M4, X3M, and M2 models, this means a direct fit and enhanced performance without compromise.
To fully leverage the capabilities of these injectors, tuning modifications will be necessary. Spool Performance stands by to support these adjustments, offering comprehensive calibration support for tuners.
