Show original supplier description
The Siemens FI11420 is a genuine Siemens Deka high-impedance fuel injector, also known as a short-style EV1 injector. It is rated to flow 42 lbs/hr at 43.5 PSI (3 BAR) and can deliver significantly more at higher pressures. These injectors are high-impedance, making them compatible with most ECUs, and they offer excellent flow capabilities in a high-impedance package. The injector features a multi-orifice tip for an optimized spray pattern, providing improved mixture preparation and atomization, which leads to better idle quality and reduced BSFC compared to injectors with a pencil stream. Key specifications include a coil resistance of 12 Ohms, a 10-15 degree cone spray pattern, and a USCAR/EV6 electrical connector. They are fitted with durable Viton upper and lower o-rings. The static flow rate is 42 lb/hr at 43.5 PSI and 48 lb/hr at 58.0 PSI. These injectors have a compact length of 48mm.
