Fuel Injector Clinic 650cc High-Z Injector Set (is406-0650h) - 1985-2003 Ford F-150 / 1993-1995 Lightning
Bring modern fuel delivery and serious performance capability to your 1985-2003 Ford F-150 or 1993-1995 Ford Lightning with the Fuel Injector Clinic 650cc High-Z injector set. This matched set of eight injectors flows 650cc/min, or 62 lbs/hr, at 43.5 PSI fuel pressure, giving modified and boosted Ford truck combinations substantially more fuel capacity while maintaining the precise control required for responsive street performance. Excellent linearity and short pulse width repeatability help provide predictable fueling across the operating range, making the is406-0650h a strong foundation for a properly tuned high-performance fuel system.
Every is406-0650h set is precisely matched using Fuel Injector Clinic's proprietary Data Match Technology. Each injector is individually serial numbered, with detailed flow matching and latency information provided on the included Data Match Sheet. FIC flow tests and rates these injectors at 43.5 PSI / 3 Bar and 90 degrees F fuel temperature using CF-16B calibration fluid. PGTUSC8 solder-in pigtails are included for the required injector plug conversion, while optional PADPUtoJ8 plug-and-play adapters allow installation without cutting or soldering the factory harness. Plug-and-play Ford ECU data is also available from Fuel Injector Clinic for tuning.

Modern 650cc Fueling for Classic Ford Trucks
Older Ford F-150 and first-generation Lightning builds can quickly outgrow their original fuel delivery capability as airflow, boost, and horsepower increase. The FIC 650cc injector brings modern high-impedance injector technology to these applications, providing substantially increased fuel capacity along with the accurate low-pulse-width behavior required for proper calibration. Whether the truck is naturally aspirated, supercharged, turbocharged, or otherwise modified, accurate injector control is essential to getting the most from the combination.
Data Match Technology for Precise Tuning
Consistent fuel delivery across all eight cylinders is critical in a performance engine. Fuel Injector Clinic precisely matches each is406-0650h set using proprietary Data Match Technology. Every injector is individually serial numbered, and detailed flow matching and latency results are supplied on the Data Match Sheet. This provides your tuner with accurate injector information for consistent cylinder-to-cylinder fueling and precise calibration throughout the operating range.
High Flow with Street-Friendly Control
Increasing injector size should not mean giving up drivability. The FIC 650cc High-Z injector combines increased fuel capacity with excellent linearity and superior short pulse width control, helping the ECU accurately meter fuel during idle, cruising, and part-throttle operation while delivering the additional volume required under higher engine loads. For street-driven performance trucks, that balance between capacity and control can be just as important as maximum injector flow.
Connector Options for a Clean Installation
The is406-0650h uses a different injector connector than the original wiring harness, so a plug conversion is required. Fuel Injector Clinic includes PGTUSC8 solder-in pigtails that can be installed in place of the original injector plugs. For owners who prefer not to cut or solder the factory harness, optional PADPUtoJ8 plug-and-play adapters provide a direct conversion between the injector and existing harness connectors.
Fuel Injector Clinic uses brand-new, unused injectors for its performance applications rather than relying on remanufactured or core-program injectors. This approach eliminates the additional uncertainty associated with previously used injector components in a performance fuel system.
