Fuel Injector Clinic 2150cc High Impedance Fuel Injector Set (1999-2006 GM 4.8L / 5.3L / 6.0L Truck Engines) - IS304-2150H
Built for extreme horsepower applications, the Fuel Injector Clinic IS304-2150H High Impedance Fuel Injector Set delivers the massive fuel flow required for today's most demanding turbocharged, supercharged, and high-boost racing combinations. This complete set of eight injectors flows an impressive 2150cc/min (200 lb/hr) at 43.5 PSI (3 Bar) and 2500cc/min (240 lb/hr) at the factory 58 PSI (4 Bar) fuel pressure. Despite their enormous capacity, these injectors offer exceptional low-speed drivability thanks to Fuel Injector Clinic's industry-leading injector matching and short pulse width control.
Unlike many large-capacity injectors that sacrifice idle quality, the IS304-2150H utilizes Fuel Injector Clinic's proprietary Data Match Technology to dynamically match each injector during production. This significantly improves injector control in the critical sub-2 millisecond pulse width range typically seen at idle and part throttle. Every injector is individually serial numbered and includes a detailed Data Match Sheet with injector-specific flow and latency data. Plug and Play GM ECU calibration data is also available from Fuel Injector Clinic to simplify tuning on supported GM engine management systems.
This injector set includes PGTDEN8 injector pigtails for wiring harness conversion. If you prefer not to modify the factory harness, optional PADPDtoGM8 Plug and Play adapters are available separately for installation without cutting or soldering. Fuel Injector Clinic specifies this connector conversion because it uses brand-new, unused injectors instead of remanufactured or core-program injectors, providing maximum reliability and consistent performance.

Important Fuel Compatibility Information
Do NOT use these injectors with VP Q16, VP Import, or any fuel containing MTBE oxygenates. The internal seal used in the 2150cc injector can swell when exposed to MTBE, significantly reducing injector flow and rendering the injector unsuitable for those fuels.
These injectors are compatible with gasoline and E85. If operating on E85 or other alcohol-based fuels, Fuel Injector Clinic recommends following proper storage and maintenance procedures to minimize the possibility of corrosion during extended periods of inactivity.

Installation and Connector Information
This injector set requires changing the injector connectors on your engine wiring harness. The included PGTDEN8 pigtails can be soldered onto the factory harness, or optional PADPDtoGM8 Plug and Play adapters can be purchased separately for a true plug-and-play installation without cutting or soldering.
Fuel Injector Clinic specifies this connector conversion because it uses brand-new, unused injectors instead of remanufactured or core-program injectors, ensuring superior reliability, consistency, and long-term performance.
FAQs
Can I use these injectors with VP Q16 or VP Import fuel?
No. These injectors should not be used with VP Q16, VP Import, or any MTBE oxygenated fuel because the internal seal can swell, restricting fuel flow and damaging injector performance.
Will such a large injector still idle well?
Yes. Fuel Injector Clinic's Dynamic Data Match Technology dramatically improves sub-2 millisecond pulse width control, allowing excellent idle quality, drivability, and tuning compared to many injectors in this flow range.
