Fuel Injector Clinic 1440cc High Impedance Injector Set (IS261-1440H) - 2017 - 2026 Audi RS3 / 2017 - 2023 Audi TT RS
The Fuel Injector Clinic IS261-1440H 1440cc High Impedance Injector Set is engineered for high-horsepower 2017-2026 Audi RS3 and 2017-2023 Audi TT RS applications that demand exceptional fuel delivery without sacrificing idle quality or everyday drivability. This complete set of five 1440cc High Impedance Ball and Seat injectors is designed to fit the factory fuel rail while utilizing Fuel Injector Clinic's latest injector technology to provide outstanding linearity, superior short pulse width repeatability, and precise fuel control throughout the RPM range.
Positioned between Fuel Injector Clinic's 1200cc and 1650cc injector offerings, the 1440cc injector delivers an excellent balance of fuel capacity and drivability. It provides enough fuel to support serious horsepower on both gasoline and E85 while retaining smooth idle characteristics for street-driven vehicles. Constructed with a stainless alloy valve, these injectors are compatible with virtually every popular performance fuel, including pump gasoline, E85, VP Q16, VP Import, FTW, and other MTBE oxygenated race fuels.
The kit includes PGTUSC5 injector pigtails for installation. Customers who prefer not to modify the factory wiring harness can choose optional PADPUtoD5 Plug and Play adaptor harnesses, available separately. Every injector set is individually matched using Fuel Injector Clinic's proprietary Data Match Technology, making tuning easier while providing exceptional fueling consistency across the operating range.
Each injector is individually serial numbered and includes a comprehensive Data Match Sheet with detailed flow and latency information. Fuel Injector Clinic flow tests every injector at 43.5 PSI (3 Bar) and 90 degrees Fahrenheit using calibration fluid. The injectors include all required factory application O-rings and are backed by Fuel Injector Clinic's lifetime warranty against defects in original manufacture.
