IFX 350 Direct Injection Injector Set

The Spool Performance IFX 350 upgraded direct injection (DI) injectors are designed for the Gen2 S63 engine platform, targeting enthusiasts seeking significant power gains. These injectors boost fuel flow by 40% compared to stock, making them suitable for high-performance builds aiming for four-digit horsepower figures. They are engineered to work seamlessly with high-pressure fuel pumps, such as the Spool Performance FX350, and can maintain consistent fuel delivery at pressures up to 390 bar. Despite their enhanced performance capabilities, the IFX 350 injectors are designed to maintain stock-like idle and low-load behaviors, ensuring smooth drivability and preserving factory control over the DI fueling system. This precision engineering allows for efficient combustion and smooth engine operation even at high power outputs. The injectors undergo extensive testing to ensure perfect fitment and compatibility with the latest Gen2 S63 tuning platforms. Included with the injectors are calibration support for existing Gen2 S63 tuning platforms and full customer support for installation and tuning modifications. It is important to note that tune modifications are required for optimal use of these injectors. The set includes 6 x IFX 350 Upgraded DI Injectors and comes with a 1-year warranty from Spool Performance. These injectors are compatible with the following BMW models: F10 M5 (2012-2017), F90 M5 (2018-2023), F06/F12/F13 M6 (2012-2019), X5 M (2015-2020), and X6 M (2015-2020).
