Fuel Injector Clinic 1200cc-D High Impedance Fuel Injector Set (2007-2013 GM 4.8L / 5.3L / 6.0L Truck Engines) - IS305-1200H-D
Engineered for serious horsepower builds, the Fuel Injector Clinic IS305-1200H-D High Impedance Fuel Injector Set delivers the fuel volume and precision required for high-performance naturally aspirated, turbocharged, supercharged, and E85 applications. Designed specifically for 2007-2013 GM 4.8L, 5.3L, and 6.0L truck engines, this complete set of eight injectors flows 1200cc-D/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. Built with Fuel Injector Clinic's latest injector technology, these injectors provide exceptional linearity, short pulse width repeatability, and outstanding drivability despite their substantial flow capacity.
This injector set features easy-to-install, drop-in fitment with the factory style connector. No plug conversion is required. Depending on your application, fuel rail spacers may be required, and the required spacers are included with the kit. Plug and Play GM ECU calibration data is available from Fuel Injector Clinic for supported GM engine management systems, helping reduce tuning time while maintaining excellent idle quality.
Each injector set is precisely matched using Fuel Injector Clinic's proprietary Data Match Technology. Every injector is individually serial numbered and includes a detailed Data Match Sheet containing injector-specific flow and latency values, providing some of the industry's most accurate injector matching for consistent cylinder-to-cylinder fuel delivery.
