Description

Up for sale is a brand-new set of (4) Fuel Injector Clinic (FIC) 1440cc High-Z Fuel Injectors, part number IS175-1440H.

Fuel Injector Clinic tests and matches injectors at 43.5 psi (3 bar) with tight tolerances and excellent short pulse-width control, improving idle stability and tunability on street, track, and race builds.

Fuel Compatibility

These injectors work with a wide range of fuel types when properly tuned:
✔ Pump Gasoline — high-output street use
✔ E85 Ethanol Blends — supports increased fueling requirements with proper ECU tuning
✔ Oxygenated Race Fuels (Q16, VP Import, FTW, etc.) — stainless internals compatible with oxygenated fuels
✔ Custom Performance Fuel Blends — suitable when ECU and fuel system are configured correctly

Proper ECU tuning is strongly recommended for each fuel type to ensure optimal performance and safe engine operation.
