Fuel Injector Clinic 775cc High Impedance Fuel Injector Set for LS1 Engines (IS301-0775H)
Support the fuel demands of your high-performance LS1 build with the Fuel Injector Clinic IS301-0775H injector set. This complete set of eight saturated high impedance fuel injectors is designed to provide the fuel volume needed for naturally aspirated, supercharged, and turbocharged combinations while maintaining excellent idle quality and outstanding street manners. Built using the latest injector technology, these injectors offer exceptional linearity and short pulse width repeatability for precise fueling and simplified tuning.
Each injector set is dynamically matched using Fuel Injector Clinic's proprietary Data Match Technology to deliver 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, giving tuners the information needed for accurate ECU calibration. Plug and Play GM ECU calibration data is available 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.
