Fuel Injector Clinic 445cc High Impedance Fuel Injector Set for LS1 Engines (IS301-0445H)
Upgrade the fueling performance of your LS1-powered build with the Fuel Injector Clinic IS301-0445H injector set. This complete set of eight saturated high impedance fuel injectors is engineered to provide exceptional fuel control, outstanding drivability, and consistent tuning results. Built using the latest injector technology, these injectors deliver excellent linearity and superior short pulse width repeatability, making them ideal for naturally aspirated performance engines as well as mild forced induction combinations.
Every Fuel Injector Clinic injector set is precisely flow matched to within one percent for exceptional cylinder-to-cylinder consistency. Each injector is individually serial numbered and accompanied by a detailed flow sheet documenting its measured performance. Plug and Play GM ECU calibration data is available directly from Fuel Injector Clinic to simplify tuning. Because Fuel Injector Clinic utilizes brand-new injectors instead of 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.
