Fuel Injector Clinic 1200cc Fuel Injector Set - High Z (is175-1200h) - 2002-2014 Subaru WRX / 2007-2021 STi
Step up the fuel system in your modified Subaru with the Fuel Injector Clinic 1200cc High-Z Fuel Injector Set. Built for 2002-2014 Subaru WRX and 2007-2021 Subaru STi applications, this set of four 1200cc saturated, high-impedance Ball and Seat injectors delivers the increased fuel capacity serious performance combinations demand while retaining the precise low-pulse-width control needed for strong drivability. Fuel Injector Clinic combines modern injector technology with its proprietary Data Match Technology to create a matched set that gives tuners accurate, consistent injector performance across the operating range. This 1200cc injector set replaces the previous IS175-1100H offering.
Every 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. Fuel Injector Clinic flow tests and rates these injectors at 43.5 PSI, or 3 Bar, with fuel temperature at 90 degrees F using CF-16B calibration fluid. Superior short pulse width control and precise matching help make these injectors easier to tune while supporting excellent drivability. The set also includes the O-rings required for the listed factory applications and is backed by Fuel Injector Clinic's lifetime warranty against failure caused by defects in original manufacture.

Wiring Requirements
The is175-1200h injector set requires an injector plug conversion. Fuel Injector Clinic includes PGTJETR4Q 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 PADPJtoD4 plug-and-play adapters can be purchased to connect the injectors to the existing wiring.
This plug conversion allows Fuel Injector Clinic to supply brand-new, unused injectors for this performance application rather than relying on remanufactured or core-program injectors.
