Fuel Injector Clinic 1200cc High Impedance Injector Set (IS403-1200H) - 2005 - 2026 Ford Mustang GT, Dark Horse, Shelby GT350, GT500, Boss 302, 1999 - 2004 Cobra & 2011 - 2026 F-150 5.0L
The Fuel Injector Clinic IS403-1200H 1200cc High Impedance Injector Set is engineered for high-performance Ford builds that require exceptional fuel delivery while maintaining excellent drivability. Flowing 1200cc/min, approximately 110 lb/hr, at 43.5 PSI or 3 Bar, these saturated high impedance injectors deliver outstanding linearity and short pulse width control, making them an excellent choice for street, strip, and forced induction applications running gasoline or E85. Previously offered as IS403-1100H, this updated injector provides increased flow while maintaining the tuning characteristics Fuel Injector Clinic is known for.
Each injector set is dynamically matched using Fuel Injector Clinic's proprietary Data Match Technology, ensuring consistent fuel delivery across all eight injectors. Every injector is individually serial numbered and includes a detailed Data Match Sheet with flow and latency information to simplify ECU calibration. The injectors are flow tested using CF-16B calibration fluid at 43.5 PSI (3 Bar) and 90 degrees Fahrenheit, and Plug and Play Ford ECU data is available directly from Fuel Injector Clinic.
This injector set includes PGTJET8Q Jetronic injector pigtails for wiring conversion. If you prefer to avoid cutting or soldering your factory harness, optional PADPJtoU8 Plug and Play adaptor harnesses are available separately. Fuel Injector Clinic includes all required O-rings for the listed factory applications, and every injector is backed by a lifetime warranty against manufacturing defects.
