Description

Up for sale is a brand-new set of (5) Fuel Injector Clinic (FIC) 2150cc High-Z Fuel Injectors, part number IS261-2150H. These extreme-flow, high-performance injectors are precision flow-matched using Fuel Injector Clinic’s Data Match Technology, which ensures consistent and predictable fuel delivery across all cylinders — a major advantage for serious performance builds and tuning.

These injectors are ideal for boosted, high-output, and extensively modified RS3 or TTRS engines where stock injectors can no longer deliver sufficient fuel volume. Whether you’re running higher boost, race gas, E85, or aggressive

Fuel Compatibility

These injectors are compatible with a wide range of fuel types when properly tuned and calibrated:
✔ Pump Gasoline — daily-driven to high-output street performance
✔ E85 Ethanol Blends — capable of handling increased fueling demands with correct ECU calibration
✔ Oxygenated Race Fuels (e.g., Q16, VP Import, FTW, etc.) — stainless internal components allow use with oxygenated fuels
✔ Custom Fuel Blends — suitable when ECU and fuel system are configured correctly

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