Fuel Injector Clinic 650cc Fuel Injector Set - High Z (is175-0650h) - 2002-2014 Subaru WRX / 2007-2021 STi
Upgrade your Subaru's fuel delivery with the Fuel Injector Clinic 650cc High-Z Fuel Injector Set, engineered for 2002-2014 Subaru WRX and 2007-2021 Subaru STi applications. This set of four 650cc saturated, high-impedance Ball and Seat injectors provides the additional fuel capacity modified combinations demand while maintaining the linearity and short pulse width repeatability needed for precise tuning and excellent drivability. Fuel Injector Clinic combines modern injector technology with its proprietary Data Match Technology to deliver a carefully matched set designed for consistent, predictable performance across the injector 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 state-of-the-art matching help make the injectors easy to tune while supporting strong 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 without cutting or soldering the factory wiring harness.

Wiring Requirements
The is175-0650h 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. For 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.
