Description

For sale is a brand-new set of (4) Fuel Injector Clinic (FIC) 2150cc High-Z Fuel Injectors, part number IS176-2150H. These extreme-flow injectors are precision flow-matched to provide consistent, high-volume fueling for boosted and high-output Subaru builds equipped with top-feed fuel rail conversions.

These injectors are flow-tested and matched under strict conditions using Fuel Injector Clinic’s proprietary process, which helps deliver reliable, consistent fuel delivery and makes tuning easier — especially on high-boost or race fuel setups.

Fuel Compatibility

These injectors are compatible with a wide range of fuel types when properly tuned:
✔ Pump Gasoline — high-output applications
✔ E85 Ethanol Blends — supports higher fueling requirements with accurate ECU calibration
✔ Oxygenated Race Fuels (Q16, VP Import, FTW, etc.) — stainless internal components allow use with performance fuels
✔ Custom Fuel Mixtures — suitable when ECU and fuel system are configured correctly

Proper ECU tuning is required for each fuel type to ensure correct air/fuel ratios and safe engine operation.
