Fuel Injector Clinic 1000cc High-Impedance Injector Set for 2007–2013 GM 4.8L, 5.3L and 6.0L Truck Engines

Fuel Injector Clinic 1000cc High-Impedance Injector Set for 2007–2013 GM 4.8L, 5.3L and 6.0L Truck Engines

Part Number: IS305-1000H

The Fuel Injector Clinic IS305-1000H is a matched set of eight high-impedance fuel injectors for 2007–2013 GM truck applications equipped with 4.8L, 5.3L, or 6.0L engines.

Each injector flows 1000 cc/min at 43.5 psi and approximately 1040 cc/min at the GM original-equipment fuel pressure of 58 psi. The set provides substantial fuel capacity for forced-induction, E85, and other high-output combinations while retaining the short-pulse control and injector characterization required for controlled startup, idle, and part-throttle operation.

The IS305-1000H is configured as a drop-in electrical fit for the supported factory injector harness. Fuel Injector Clinic also supplies the application-specific O-rings and fuel-rail spacers that may be required for proper installation.

Fuel Injector Clinic individually serial-numbers and tests each injector using its Data Match Technology process. The supplied Data Match sheet includes flow and latency information for accurate ECU configuration.

Technical Specifications

Flow Rating

• 1000 cc/min at 43.5 psi differential fuel pressure
• Approximately 85 lb/hr at 43.5 psi differential fuel pressure
• Approximately 1040 cc/min at 58 psi differential fuel pressure
• Approximately 100 lb/hr at 58 psi differential fuel pressure
• Flow tested using CF-16B calibration fluid at approximately 90°F

Electrical Configuration

• Saturated, high-impedance injector design
• Compatible with conventional saturated injector drivers
• No external injector resistor pack required in supported applications
• Factory-compatible electrical connection for the listed 2007–2013 GM truck applications
• No injector-harness pigtails or plug-conversion adapters required for the supported factory application

Injector Characterization

• Each injector is individually serial-numbered
• Injector-set results are supplied on a Fuel Injector Clinic Data Match sheet
• Flow and latency information is provided for ECU configuration
• GM ECU data is available from Fuel Injector Clinic
• Injector data must be entered correctly for the ECU, fuel pressure, and fuel being used

Application Notes

• This injector set is designed for 2007–2013 GM truck applications equipped with 4.8L, 5.3L, or 6.0L engines.
• This listing is for one matched set of eight injectors.
• Fuel Injector Clinic identifies the IS305-1000H as a drop-in plug fit for the supported factory injector harness.
• Fuel-rail spacers may be required depending on the exact intake-manifold and fuel-rail configuration; the required spacers are supplied with the injector set.
• Application-specific O-rings are included for the listed factory application.
• This product listing does not identify 6.2L truck applications as supported. Confirm injector fitment separately for a 6.2L application.
• Aftermarket fuel rails, intake manifolds, injector bungs, or unusual component combinations may change the required injector length, O-ring size, rail spacing, or electrical connection.
• Confirm fitment before ordering when using non-factory rails, intake manifolds, or injector-harness components.
• The published 1000 cc/min rating is measured at 43.5 psi differential fuel pressure.
• At the GM factory pressure of 58 psi, the injectors flow approximately 1040 cc/min.
• Injector flow changes with differential fuel pressure; ECU configuration must reflect the actual base pressure and manifold-pressure reference strategy.
• Injector characterization data must be entered into the ECU rather than relying only on the nominal flow rating.
• Fuel-system capacity, pump selection, regulator capacity, line sizing, filtration, and electrical supply must be adequate for the intended fuel and power level.
• Power capability is not specified because required injector capacity depends on fuel type, base pressure, brake-specific fuel consumption, duty-cycle target, and engine configuration.
