Fuel Injector Clinic 1650cc Fuel Injector Set - High Z (is175-1650h) - 2002-2014 Subaru WRX / 2007-2021 STi
Give a high-horsepower Subaru the fuel capacity it needs without sacrificing the drivability you want on the street. The Fuel Injector Clinic 1650cc High-Z Fuel Injector Set is engineered for 2002-2014 Subaru WRX and 2007-2021 Subaru STi applications, combining serious 1650cc/min flow capability with excellent idle performance, precise short pulse width control, and Fuel Injector Clinic's Data Match Technology. This four-injector set uses saturated, high-impedance Ball and Seat injectors and provides the headroom needed for demanding E85, gasoline, and race-fuel combinations.
Unlike the 2150cc version, Fuel Injector Clinic's 1650cc high-impedance injector is compatible with MTBE oxygenated race fuels. Its stainless alloy valve construction allows compatibility with pump gasoline, E85, Q16, VP Import, FTW, and other MTBE oxygenated race fuels. Each injector is individually serial numbered and precisely matched using Fuel Injector Clinic's proprietary Data Match Technology, with the results supplied on a detailed Data Match Sheet. The injectors are flow tested and rated at 43.5 PSI, or 3 Bar, at 90 degrees F fuel temperature using CF-16B calibration fluid.

Wiring Requirements
This injector set requires an injector plug conversion. The included PGTJETR4Q pigtails can be soldered into the vehicle's wiring harness to replace the existing injector plugs. For an installation that does not require cutting or soldering the factory harness, optional PADPJtoD4 plug-and-play adapters can be purchased to connect these injectors to the factory wiring.
Fuel Injector Clinic uses this plug conversion because it chooses brand-new, unused injectors for its performance applications rather than relying on remanufactured or core-program injectors.
