Fuel Injector Clinic 2150cc High Impedance Fuel Injector Set for LS1 Engines (IS301-2150H)
Built for the most demanding high-horsepower LS1 combinations, the Fuel Injector Clinic IS301-2150H injector set delivers massive fuel flow without sacrificing low-speed control. This complete set of eight saturated high impedance injectors utilizes the latest injector technology and Fuel Injector Clinic's advanced Data Match Technology to provide exceptional short pulse width performance, allowing for improved idle quality and part-throttle drivability despite its enormous 2150 cc/min flow capacity. Whether your build is powered by boost, nitrous, or both, these injectors are engineered to support extreme horsepower applications.
Each injector is dynamically matched during production using Fuel Injector Clinic's proprietary Data Match Technology and is individually serial numbered. Every set includes a comprehensive Data Match Sheet with detailed flow matching and latency values for accurate ECU calibration. Plug and Play GM ECU calibration data is available directly from Fuel Injector Clinic. The kit includes PGTDEN8 injector pigtails, while optional PADPDtoU8 Plug and Play adapters are available separately for installers who prefer not to modify the factory wiring harness.
Important Fuel Compatibility: These injectors are compatible with pump gasoline and E85, but must not be used with VP Import, Q16, or any other MTBE oxygenated race fuels. The internal seal used in the 2150cc injector can swell when exposed to MTBE oxygenated fuels, resulting in a significant reduction in injector flow. Fuel Injector Clinic also recommends following proper storage procedures when using alcohol-based fuels such as E85 to help prevent corrosion during extended periods of inactivity.

FAQs
Do these injectors require wiring modifications?
Yes. The IS301-2150H includes PGTDEN8 injector pigtails for wiring conversion. Optional PADPDtoU8 Plug and Play adapters are available separately for installers who prefer a no-cut installation.
Can these injectors be used with Q16 or VP Import race fuel?
No. Fuel Injector Clinic specifically advises against using the IS301-2150H with VP Import, Q16, or any other MTBE oxygenated fuels because the injector's internal seal can swell, reducing fuel flow. When running E85 or other alcohol-based fuels, proper storage procedures should also be followed to help prevent corrosion during extended periods of inactivity.
