Fuel Injector Clinic 365cc High Impedance Fuel Injector Set for LS1 Engines (IS301-0365H)
Upgrade your LS1 fuel system with the Fuel Injector Clinic IS301-0365H injector set. Designed for enthusiasts looking for improved fuel delivery while maintaining excellent street manners, this complete set of eight saturated high impedance injectors delivers outstanding idle quality, smooth drivability, and predictable tuning. Utilizing the latest injector technology, these injectors offer exceptional linearity and short pulse width repeatability, making them an excellent choice for naturally aspirated and mild forced induction LS1 combinations.
Each injector set is precisely flow matched to within one percent to ensure balanced fuel delivery across every cylinder. Every injector is individually serial numbered and includes a detailed flow sheet documenting its performance. Because Fuel Injector Clinic uses brand-new injectors rather than remanufactured units, this kit 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.
