Fuel Injector Clinic 1200cc High Impedance Fuel Injector Set (2007-2013 GM 4.8L / 5.3L / 6.0L Truck Engines) - IS305-1200H
Upgrade your 2007-2013 GM 4.8L, 5.3L, or 6.0L truck engine with the Fuel Injector Clinic IS305-1200H High Impedance Fuel Injector Set. Designed for serious street and racing applications, this complete set of eight injectors flows 1200cc/min (110 lb/hr) at 43.5 PSI (3 Bar) and 1350cc/min (130 lb/hr) at the factory 58 PSI (4 Bar) fuel pressure. Utilizing Fuel Injector Clinic's latest injector technology, these injectors provide excellent linearity, exceptional short pulse width repeatability, and outstanding drivability while supporting the fuel demands of high-horsepower naturally aspirated, supercharged, turbocharged, and E85 combinations.
This injector set includes PGTJETR8 injector pigtails for wiring harness conversion. If you prefer not to modify the factory harness, optional PADPJtoU8 Plug and Play adapters are available separately, allowing installation without cutting or soldering. Depending on your application, fuel rail spacers may be required, and the necessary spacers are included. Plug and Play GM ECU calibration data is also available from Fuel Injector Clinic for supported GM engine management systems.
Every injector set is precisely matched using Fuel Injector Clinic's proprietary Data Match Technology. Each injector is individually serial numbered and supplied with a comprehensive Data Match Sheet containing injector-specific flow and latency information, providing some of the most accurate injector matching available for consistent fueling and easier tuning. This injector was previously offered under part number IS305-1100H.

Installation and Connector Information
This injector set requires changing the injector connectors on your vehicle's wiring harness. The included PGTJETR8 pigtails can be soldered onto the factory harness, or optional PADPJtoU8 Plug and Play adapters can be purchased separately to eliminate the need for cutting or soldering.
Fuel Injector Clinic specifies this connector conversion because it uses brand-new, unused injectors rather than remanufactured or core-based injectors, providing greater long-term reliability and consistent performance for demanding performance applications.
FAQs
Why do these injectors require a connector conversion?
The IS305-1200H uses brand-new injector technology that requires a different connector than the factory harness. Pigtails are included, and optional Plug and Play adapters are available if you prefer not to modify the wiring.
What is the difference between IS305-1200H and IS305-1100H?
The IS305-1200H is the updated replacement for the previous IS305-1100H part number, offering the same application with updated injector naming based on current flow specifications.
