The Fuel Injector Clinic IS403-0775H 775cc High Impedance Injector Set is engineered for Ford enthusiasts looking to support serious naturally aspirated, supercharged, or turbocharged power while maintaining factory-like drivability. Flowing 775cc/min, approximately 74 lb/hr, at 43.5 PSI or 3 Bar, these saturated high impedance Ball & Seat injectors offer excellent idle quality, outstanding short pulse width control, and the precise fuel delivery needed for modern high-performance builds running gasoline or E85.
The IS403-0775H is a true drop-in injector for both physical size and factory electrical connector, eliminating the need for wiring modifications, pigtails, or adaptor harnesses. Plug and Play Ford ECU calibration data is available directly from Fuel Injector Clinic, making tuning easier while providing accurate injector characterization for consistent performance.
Every injector set is precisely matched using Fuel Injector Clinic's proprietary Data Match Technology. Each injector is individually serial numbered and supplied with a comprehensive Data Match Sheet containing detailed flow and latency values. Fuel Injector Clinic tests and rates every injector using CF-16B calibration fluid at 43.5 PSI (3 Bar) and 90 degrees Fahrenheit.
