1650cc High-Impedance Fuel Injector Set

The Fuel Injector Clinic 1650cc high-impedance injectors are designed for performance applications, offering a high flow rate suitable for supporting increased horsepower on E85 and gasoline fuels. These injectors are compatible with a wide range of fuel types, including pump gasoline, E85, Q16, VP Import, FTW, and other MTBE oxygenated race fuels, thanks to their stainless alloy valve construction. Each injector set is precisely matched using Fuel Injector Clinic's proprietary Data Match Technology, with individual serial numbers and detailed results provided on a Data Match Sheet. This ensures the most complete flow matching and latency value information available. The injectors are flow tested and rated at 43.5psi (3Bar) at 90°F fuel temperature. They also feature superior short pulse width control for easy tuning and excellent drivability. These injectors are intended for Subaru WRX models from 2002-2014 and STi models from 2007 onwards. They also fit 2004-2006 STi models with a WRX tumbler conversion. The set includes all o-rings needed for factory application fitment. However, a modification to the wiring harness is required. This can be achieved by soldering in the included pigtails or by purchasing optional plug-and-play adapters. Every injector comes with a lifetime warranty against failure caused by manufacturing defects.
