Upgrade the fuel system on your Gen 3 HEMI with the Fuel Injector Clinic 650cc High-Z Fuel Injector Set IS153-0650H. Designed for Dodge SRT8 and compatible 5.7L HEMI applications, this complete eight-injector set provides additional fueling capacity for performance combinations that demand more than the factory injectors can reliably supply. Each injector flows 650cc/min, or 62 lbs/hr, at 43.5 psi, with output increasing to approximately 750cc/min, or 72 lbs/hr, at the factory 58 psi fuel pressure. For camshaft upgrades, increased airflow, and other performance modifications, these injectors provide additional fueling headroom while retaining the control required for good street manners.

Fuel Injector Clinic’s matching process is one of the biggest advantages of this set. Each injector is individually serial numbered and precisely matched using FIC’s proprietary Data Match Technology. A Data Match Sheet is supplied with the set, providing detailed flow matching and latency information that gives your tuner the data needed to accurately calibrate the fuel system. FIC also provides plug-and-play Dodge ECU data, helping simplify the calibration process for compatible factory ECU applications.

Good injector performance is about more than maximum flow. FIC designed these injectors for excellent linearity and short pulse width repeatability, which is especially important during idle, cruising, and other low-load conditions where the injectors operate for very short periods. Superior short pulse width control allows a properly calibrated engine to maintain smoother drivability while still providing the additional fuel required at higher engine loads. This makes the IS153-0650H a strong choice for performance enthusiasts who still regularly drive their Gen 3 HEMI on the street.

Installation is straightforward because the injectors are configured as a drop-in replacement for both size and electrical plug on the listed applications. FIC also includes the required O-rings for factory fitment, reducing the need to source additional installation hardware. If your vehicle uses an aftermarket intake manifold, fuel rail, or another non-standard fuel system configuration, injector fitment should be verified before ordering.

For naturally aspirated Gen 3 HEMI combinations that have outgrown their factory fueling capacity, the Fuel Injector Clinic 650cc High-Z Injectors offer an excellent balance between additional flow and street-friendly control. With eight flow-matched injectors, detailed calibration data, direct-fit installation, and FIC’s lifetime warranty against manufacturing defects, the IS153-0650H provides a dependable foundation for a properly tuned HEMI performance build.
