Fuel Injector Clinic 2150cc High Impedance Fuel Injector Set for Small Block Chevy Gen II Engines (IS300-2150H)
When your Small Block Chevy Gen II combination demands maximum fuel delivery without sacrificing drivability, the Fuel Injector Clinic IS300-2150H High Impedance Fuel Injector Set delivers. This complete set of eight injectors flows an incredible 2150cc/min (200 lb/hr) at 43.5 PSI (3 Bar) and 2500cc/min (240 lb/hr) at the factory-style 58 PSI (4 Bar) fuel pressure. As the largest high impedance injectors offered by Fuel Injector Clinic, they are engineered for extreme horsepower applications while maintaining outstanding idle quality and low pulse width control. They are an excellent choice for high-horsepower E85-powered race and street builds.
Unlike many ultra-large injectors, the IS300-2150H utilizes Fuel Injector Clinic's proprietary Data Match Technology to dynamically match each injector during production. This advanced matching dramatically improves injector consistency in the sub-2 millisecond pulse width range, allowing the ECU to maintain excellent idle quality, part-throttle drivability, and precise fuel control despite the injector's massive flow capacity. Every injector is individually serial numbered and supplied with a comprehensive Data Match Sheet containing injector-specific flow and latency information. Plug and Play GM ECU calibration data is also available from Fuel Injector Clinic.
This injector set includes PGTDEN8 Denso injector pigtails for wiring harness conversion. If you prefer to avoid modifying your factory wiring harness, optional PADPDtoJ8 Plug and Play adapters are available separately. Fuel Injector Clinic utilizes brand-new injectors instead of remanufactured or core-exchange injectors, providing superior reliability and long-term performance for demanding racing applications.
Important Fuel Compatibility Notice: The IS300-2150H features an internal seal that is not compatible with MTBE oxygenated fuels. Do not use these injectors with VP Import, Q16, or any other MTBE oxygenated fuels. These injectors are an excellent choice for E85 and conventional gasoline applications. If running alcohol-based fuels such as E85, follow Fuel Injector Clinic's recommended maintenance procedures to minimize the potential for corrosion during extended periods of storage.

Installation and Fuel Compatibility
This injector set requires changing the injector connectors on your engine wiring harness. The included PGTDEN8 pigtails can be soldered onto the factory harness, while optional PADPDtoJ8 Plug and Play adapters allow installation without cutting or soldering the original wiring.
Do not use these injectors with VP Import, Q16, or any other MTBE oxygenated fuels. Exposure to MTBE can cause the internal injector seal to swell, significantly reducing injector flow. These injectors are designed for use with gasoline and E85. When using E85 or other alcohol-based fuels, Fuel Injector Clinic recommends following proper storage and maintenance procedures to reduce the possibility of corrosion during extended periods of non-use.
FAQs
Are these injectors compatible with E85?
Yes. The IS300-2150H is an excellent injector for E85 and gasoline applications. However, it should never be used with VP Import, Q16, or any fuel containing MTBE oxygenates.
Do these injectors require wiring modifications?
Yes. The included PGTDEN8 pigtails are designed for wiring harness conversion. Optional PADPDtoJ8 Plug and Play adapters are available separately for installation without cutting or soldering the factory wiring harness.
