Fuel Injector Clinic 650cc High Impedance Fuel Injector Set (2007-2013 GM 4.8L / 5.3L / 6.0L Truck Engines) - IS305-0650H
Step up the fuel capacity of your 2007-2013 GM 4.8L, 5.3L, or 6.0L truck engine with the Fuel Injector Clinic IS305-0650H High Impedance Fuel Injector Set. Designed for performance street, naturally aspirated, supercharged, and turbocharged applications, this complete set of eight injectors flows 650cc/min (62 lb/hr) at 43.5 PSI (3 Bar) and 750cc/min (72 lb/hr) at the factory 58 PSI (4 Bar) fuel pressure. Built using the latest injector technology, these injectors deliver exceptional linearity, outstanding short pulse width repeatability, and smooth drivability from idle through wide open throttle.
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 necessary spacers are included with the kit. Plug and Play GM ECU calibration data is also available from Fuel Injector Clinic for supported GM engine management systems, helping simplify tuning while maintaining factory-like drivability.
Every injector set is precisely matched using Fuel Injector Clinic's proprietary Data Match Technology. Each 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.
