ID1750-XDS | Injector Dynamics | 1750.48.11.WRX

The '1750.48.11.WRX' code means this ID1750-XDS is a direct, drop-in fit for specific Subaru WRX/STi models. The 48mm is the required short body length for the OEM fuel rail, and the WRX confirms the seal and spacer setup for the factory manifold, simplifying the Subaru injector upgrade.

Yes, it is absolutely essential. For the ultra-fine orifices of the ID1750-XDS, a 10-micron stainless steel fuel filter is required. This prevents contamination from the fuel system, which is critical for maintaining the injector's performance and preventing clogs, especially when running E85.

The ID1750-XDS can achieve an extremely low minimum pulse width of approximately 0.60 milliseconds or less. This feature, combined with its advanced control, is key to achieving a smooth, stable, and stoichiometric idle on a large displacement or big turbo Subaru Boxer engine despite the injector's massive flow rating.

No. The ID1750-XDS requires significantly higher fuel volume than stock. You must install a high-volume fuel pump, upgraded fuel lines, and a high-flow adjustable fuel pressure regulator (FPR) to maintain the required stable rail pressure under high boost conditions.

Yes. Injector Dynamics provides highly accurate calibration data (latency and flow tables) directly compatible with popular Subaru tuning software and platforms, including Cobb Accessport (via custom tuning) and many standalone ECUs, ensuring accurate and reliable custom tuning.
