1440cc Fuel Injectors

The Fuel Injector Clinic 1440cc fuel injector set is engineered for high-performance applications in Subaru WRX (2002-2014) and STI (2007+) models. These injectors utilize a high impedance Bosch core and are fully compatible with E85 fuel, as well as a wide range of race fuels including Q16, VP Import, and FTW. They are designed to provide excellent idle characteristics for street use while offering sufficient fuel delivery to support significant horsepower gains on both E85 and gasoline. Each injector in this set is precisely flow-matched and individually serial numbered through Fuel Injector Clinic's proprietary Data Match Technology. This ensures the most comprehensive flow matching and latency value information available, making them easy to tune and resulting in great drivability. The injectors are flow-tested and rated at 43.5psi (3Bar) at 90°F fuel temperature. The stainless alloy valve construction allows compatibility with pump gasoline, E85, and various oxygenated race fuels. Installation of these injectors requires modification to the wiring harness, as they use a different plug type than the factory application. Pigtails are included for soldering, or optional plug-and-play adapters can be purchased separately to avoid cutting or soldering. This approach ensures the use of brand-new, unused injectors, a commitment Fuel Injector Clinic maintains for performance applications to minimize the risk of failure associated with remanufactured components. The set includes all necessary o-rings for a factory fitment.
