Fuel Injector Clinic 445cc High Impedance Injector Set (IS403-0445H) - 2005 - 2026 Ford Mustang GT, 2015 - 2020 Shelby GT350, 2020 Shelby GT500, 2012 - 2013 Boss 302 & 1999 - 2004 Cobra
The Fuel Injector Clinic IS403-0445H 445cc High Impedance Injector Set gives modified Ford Mustang combinations the additional fuel capacity needed for performance upgrades while preserving the precise low-speed control required for smooth idle quality and dependable street manners. Rated at 445cc/min, approximately 42 lb/hr, at 43.5 PSI or 3 Bar, this complete set of eight saturated High-Z injectors is a strong choice for naturally aspirated and forced-induction builds that need more fuel flow than the factory injectors can provide.
The IS403-0445H is designed as a drop-in replacement for both injector size and electrical connector. No wiring modifications, pigtails, plug conversions, or adaptor harnesses are required for the listed factory applications. Excellent linearity, superior short pulse width control, and tight manufacturing tolerances help make these injectors easy to tune across idle, part-throttle, and wide-open-throttle operation. Plug and Play Ford ECU data is also available from Fuel Injector Clinic.
Each set is precisely flow matched to within 1 percent. Every injector is individually numbered, and the included detailed flow sheet provides the results for each injector in the set. Fuel Injector Clinic flow tests and rates these injectors at 43.5 PSI using CF-16B calibration fluid maintained at 90 degrees Fahrenheit. All O-rings needed for the listed factory applications are included, and every injector is covered by Fuel Injector Clinic's lifetime warranty against failure caused by defects in original manufacture.
