Fuel Injector Clinic 650cc High Impedance Fuel Injector Set for LS1 Engines (IS301-0650H)
Give your LS1-powered build the fuel delivery it needs with the Fuel Injector Clinic IS301-0650H injector set. This complete set of eight saturated high impedance fuel injectors is engineered to support higher horsepower combinations while maintaining excellent idle quality and everyday drivability. Built using the latest injector technology, these injectors deliver outstanding linearity and exceptional short pulse width repeatability, making them an excellent choice for naturally aspirated, supercharged, and turbocharged LS1 applications.
Each injector set is dynamically matched using Fuel Injector Clinic's proprietary Data Match Technology to provide exceptional cylinder-to-cylinder consistency. Every injector is individually serial numbered and includes a comprehensive Data Match Sheet with detailed flow matching and latency values for more precise ECU calibration. Plug and Play GM ECU calibration data is available directly from Fuel Injector Clinic. This kit also includes PGTUSC8 injector pigtails, while optional PADPUtoJ8 Plug and Play adapters are available separately for installers who prefer not to modify the factory wiring harness.
