Overview

The Siemens FI11354 is a set of high-impedance fuel injectors designed for enhanced engine performance. These injectors flow 46.5 lbs/hr at 43.5 PSI and are capable of higher flow rates at increased pressures. They are linear and controllable at low pulse widths, making them suitable for ULEV applications and allowing for larger injector sizes without compromising idle or low-speed drivability.
Show original supplier description
The Siemens FI11354 is a set of genuine Siemens DEKA High Impedance Fuel Injectors, specifically the long style with an EV6/USCAR connector. These injectors are engineered for high performance, offering a static flow rate of 46.5 lbs/hr at 43.5 PSI (3 BAR), with the ability to flow significantly more at higher pressures. Their high impedance design (12 Ohms coil resistance) ensures compatibility with most factory ECUs and their drivers, eliminating the need for ECM/PCM modifications. Despite their high flow rate, these injectors provide linear and controllable performance at low pulse widths, making them suitable for demanding applications, including ULEV, and allowing for the use of larger injectors without sacrificing idle or low-speed drivability. The optimized spray pattern features a multi-orifice tip for improved mixture preparation and atomization, resulting in lower BSFC and better idle quality compared to injectors with a less refined spray. Key specifications include a 20-degree cone spray pattern, USCAR electrical connector, and fitted Viton upper and lower O-rings for durability. The static flow rate at 58.0 PSI (400kPa) is 53.7 lbs/hr (6.77 g/s = 552 cc/min), and the dynamic flow rate at a 2.5ms pulse width and 100Hz is 11.42 mg/pulse. These injectors are noted as a direct fit for LS2 and LS7 applications and are built for high-pressure, harsh environments.
