Fuel Injector Clinic 650cc High Impedance Injector Set (IS403-0650H) - 2005 - 2026 Ford Mustang GT, 2015 - 2020 Shelby GT350, 2020 Shelby GT500, 2012 - 2013 Boss 302 & 1999 - 2004 Cobra
The Fuel Injector Clinic IS403-0650H 650cc High Impedance Injector Set delivers the additional fuel capacity required by modified Ford Mustang combinations while maintaining the precise low-speed control needed for smooth idle quality and confident street drivability. Rated at 650cc/min, approximately 62 lb/hr, at 43.5 PSI or 3 Bar, this set of eight saturated Ball & Seat injectors is well suited for naturally aspirated and forced-induction builds that have outgrown the capacity of the factory injectors.
The IS403-0650H is designed as a drop-in replacement for both injector size and electrical connector. No plug conversion, wiring modification, pigtails, or adaptor harnesses are required for the listed factory applications. Excellent linearity and repeatable short pulse width operation help make these injectors easier to calibrate across idle, part-throttle, and wide-open-throttle conditions. Plug and Play Ford ECU data is available from Fuel Injector Clinic to provide tuners with accurate injector characterization.
Each set is precisely matched using Fuel Injector Clinic's proprietary Data Match Technology. Every injector is individually serial numbered, and the included Data Match Sheet provides detailed flow and latency information for the matched set. Fuel Injector Clinic tests and rates its injectors at 43.5 PSI using CF-16B calibration fluid maintained at 90 degrees Fahrenheit. The required O-rings for the listed factory applications are included, and each injector is covered by a lifetime warranty against failure caused by defects in original manufacture.
