Fuel Injector Clinic 525cc High-Z Injector Set (is406-0525h) - 1985-2003 Ford F-150 / 1993-1995 Lightning
Upgrade the fuel system in your 1985-2003 Ford F-150 or 1993-1995 Ford Lightning with the Fuel Injector Clinic 525cc High-Z injector set. This matched set of eight injectors flows 525cc/min, or 50 lbs/hr, at 43.5 PSI fuel pressure, providing increased fuel capacity for modified Ford truck combinations while retaining the precise control needed for strong drivability. Excellent linearity, short pulse width repeatability, and tight manufacturing tolerances help deliver predictable fueling from idle and part throttle through higher-load operation.
Fuel Injector Clinic precisely flow matches each high-performance injector set to within 1%. Every injector is individually numbered, with its results documented on the detailed flow sheet included with the set. The is406-0525h is flow tested and rated 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 provide an installation option without cutting or soldering the factory harness. Plug-and-play Ford ECU data is also available from Fuel Injector Clinic.

525cc Fueling for Performance Ford Trucks
Modified F-150 and first-generation Lightning combinations can quickly demand more fuel as airflow and horsepower increase. The FIC 525cc injector provides additional fuel capacity while maintaining the accurate low-speed control needed for proper calibration and street drivability. With 525cc/min of flow, the is406-0525h gives performance-oriented Ford truck builds increased fueling capability without sacrificing the precise injector behavior needed during everyday driving.
Precisely Flow Matched to Within 1%
Consistent fuel delivery across all eight cylinders is critical to a properly tuned performance engine. Fuel Injector Clinic precisely flow matches each is406-0525h injector set to within 1%, helping minimize injector-to-injector variation. Every injector is individually numbered, and its results are documented on the detailed flow sheet included with the set. This gives your tuner valuable injector-specific information for consistent cylinder-to-cylinder fueling and accurate calibration.
High Flow with Street-Friendly Control
A performance injector needs to accurately meter small quantities of fuel during idle and cruising while supplying additional fuel as engine load increases. Fuel Injector Clinic combines 525cc/min of flow with excellent linearity, superior short pulse width control, and tight manufacturing tolerances. These characteristics help make the injectors easier to tune while supporting the drivability expected from a street-driven performance truck.
Connector Options for a Clean Installation
The is406-0525h requires an injector connector conversion for the listed applications. Fuel Injector Clinic includes PGTUSC8 solder-in pigtails, allowing the existing injector connectors on the wiring harness to be replaced. Optional PADPUtoJ8 plug-and-play adapters provide an alternative for owners who prefer installation without cutting or soldering the factory wiring harness.
Fuel Injector Clinic uses brand-new, unused injectors for its performance applications rather than relying on remanufactured or core-program injectors. This approach avoids introducing the additional uncertainty associated with previously used injector components into a performance fuel system.
