Fuel Injector Clinic 1200cc-D High-Z Injector Set — 2007–2013 GM 4.8L / 5.3L / 6.0L Truck
Part Number: IS305-1200H-D
Fuel Injector Clinic IS305-1200H-D is an eight-injector high-impedance set developed for 2007–2013 GM truck applications using 4.8L, 5.3L, and 6.0L engines. The 1200cc-D injectors flow 1200 cc/min / 110 lb/hr at 43.5 psi differential fuel pressure and 1350 cc/min / 130 lb/hr at the OE 58 psi / 4 bar fuel pressure.
Each injector set is individually serial numbered and matched using Fuel Injector Clinic's Data Match Technology, with the resulting flow and latency information supplied on the included Data Match Sheet. FIC also provides plug-and-play GM ECU injector data for supported tuning platforms, helping provide predictable fueling behavior from short-pulse-width operation through high-load use.

Application Notes
- FIC catalogs IS305-1200H-D specifically for 2007–2013 GM truck applications with 4.8L, 5.3L, and 6.0L engines.
- This is the distinct FIC 1200cc-D product, not the standard IS305-1200H & PGTJETR8Q injector-and-pigtail configuration.
- Fuel Injector Clinic does not list a separate pigtail or plug-and-play adapter part number as part of the current IS305-1200H-D product code.
- Fuel-rail spacers may be required depending on the application; FIC states that the required spacers are provided.
- FIC supplies the O-rings required for the listed factory application. Aftermarket rails, manifolds, or unusual installations should be checked for dimensional compatibility before ordering.
- Fuel pumps, regulator, fuel rails, filters, plumbing, ECU, sensors, and ECU configuration/tuning are not included.
Emissions and Competition-Use Notice
