Fuel Injector Clinic 525cc High-Z Injector Set (is402-0525h) - 1987-2004 Mustang GT / 1993-1998 Mustang Cobra
Upgrade the fuel system in your 1987-2004 Ford Mustang GT or 1993-1998 Mustang Cobra 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 fueling capability for modified Mustang combinations while retaining the precise control needed for excellent street manners. Superior short pulse width control, excellent linearity, and tight manufacturing tolerances help deliver predictable fueling at idle, part throttle, and under load.
Fuel Injector Clinic precisely flow matches each high-performance injector set to within 1%. Every injector is individually numbered, and its results are documented on the detailed flow sheet included with the set. The is402-0525h includes PGTUSC8 solder-in pigtails for the required injector connector conversion, while optional PADPUtoJ8 plug-and-play adapters provide an installation option without cutting or soldering the factory wiring harness. FIC also makes plug-and-play Ford ECU data available to support accurate calibration.

525cc Performance Fueling with Street-Friendly Control
The FIC 525cc injector provides additional fuel capacity for Mustang combinations that have outgrown their existing injectors without unnecessarily jumping to an extreme injector size. Its 525cc/min flow capacity is combined with excellent linearity and superior short pulse width control, helping the ECU accurately manage fuel delivery during idle and part-throttle operation while supplying additional fuel as engine demand increases.
Precisely Flow Matched to Within 1%
Consistent fuel delivery across all eight cylinders is essential for a properly tuned performance engine. Fuel Injector Clinic precisely flow matches each is402-0525h injector set to within 1%, helping minimize injector-to-injector variation. Every injector is individually numbered, and the detailed flow sheet included with the set documents the results for each injector. This gives your tuner reliable information for consistent cylinder-to-cylinder fueling and accurate calibration.
Built for Tunability and Drivability
Fuel Injector Clinic combines tight manufacturing tolerances with superior short pulse width control to create an injector that is easy to work with during calibration. Accurate low-pulse-width behavior is especially important during idle and light-load operation, where precise fuel control directly affects drivability. The is402-0525h delivers increased performance capability while retaining the predictable injector behavior needed for a street-driven Mustang.
Connector Options for Your Mustang
The is402-0525h requires an injector connector conversion for the listed Mustang applications. Fuel Injector Clinic includes PGTUSC8 solder-in pigtails, allowing the existing injector plugs on the vehicle wiring harness to be replaced. Optional PADPUtoJ8 plug-and-play adapters are available for owners who prefer installation without cutting or soldering the factory harness. FIC uses brand-new, unused injectors for its performance applications rather than relying on remanufactured or core-program injectors.
