Fuel Injector Clinic 1440cc Fuel Injector Set - High Z (is175-1440h) - 2002-2014 Subaru WRX / 2007-2021 STi
Bridge the gap between Fuel Injector Clinic's 1200cc and 1650cc offerings with the FIC 1440cc High-Z Fuel Injector Set for 2002-2014 Subaru WRX and 2007-2021 Subaru STi applications. This set of four 1440cc saturated, high-impedance Ball and Seat injectors delivers the fuel capacity needed for serious performance builds while maintaining the excellent idle characteristics and short pulse width control that matter on a street-driven Subaru. Whether the combination runs gasoline, E85, or race fuel, the is175-1440h gives tuners substantial fueling capability without jumping all the way to a larger 1650cc or 2150cc injector.
Fuel Injector Clinic builds the 1440cc injector with stainless alloy valve construction for broad fuel compatibility, including pump gasoline, E85, Q16, VP Import, FTW, and other MTBE oxygenated race fuels. Each injector is individually serial numbered and precisely matched using FIC's proprietary Data Match Technology, with detailed flow matching and latency information supplied on the included 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. Superior short pulse width control and precise matching help provide excellent drivability and predictable injector behavior for tuning.

Wiring Requirements
The is175-1440h injector set requires an injector plug conversion. PGTUSC4 pigtails are included and 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 PADPUtoD4 plug-and-play adapters can be purchased to connect the injectors to the existing wiring.
This plug conversion allows Fuel Injector Clinic to use brand-new, unused injectors for its performance applications rather than relying on remanufactured or core-program injectors.
