Fuel Injector Clinic 775cc Fuel Injector Set - High Z (is175-0775h) - 2002-2014 Subaru WRX / 2007-2021 STi
Upgrade the fuel system in your modified Subaru with the Fuel Injector Clinic 775cc High-Z Fuel Injector Set. Designed for 2002-2014 Subaru WRX and 2007-2021 Subaru STi applications, this set of four 775cc saturated, high-impedance Ball and Seat injectors provides increased fueling capacity along with the linearity, short pulse width repeatability, and drivability demanded from a properly tuned street or performance build. Fuel Injector Clinic combines modern injector technology with its proprietary Data Match Technology to deliver a precisely matched set engineered for predictable fuel delivery across the operating range.
Each injector is individually serial numbered and precisely matched using Fuel Injector Clinic's Data Match Technology, with detailed flow matching and latency information supplied on the included Data Match Sheet. FIC flow tests and rates these injectors at 43.5 PSI, or 3 Bar, at 90 degrees F fuel temperature using CF-16B calibration fluid. Superior short pulse width control and precise matching help make these injectors easier to tune while maintaining excellent drivability. The set includes PGTUSC4 solder-in pigtails and the O-rings required for the listed factory applications, while optional PADPUtoD4 plug-and-play adapters provide an installation option that does not require cutting or soldering the factory wiring harness.

Wiring Requirements
The is175-0775h injector set requires an injector plug conversion. Fuel Injector Clinic includes PGTUSC4 pigtails that can be soldered into the vehicle's wiring harness to replace the existing injector plugs. If you prefer an installation without cutting or soldering the factory harness, optional PADPUtoD4 plug-and-play adapters can be purchased to connect the injectors to the existing wiring.
This plug conversion allows Fuel Injector Clinic to provide brand-new, unused injectors for its performance applications rather than relying on remanufactured or core-program injectors.
