Fuel Injector Clinic 525cc High-Z Injector Set (is407-0525h) - 2021-2026 F-150 5.0L with Whipple
Upgrade the fuel delivery on your Whipple-supercharged 2021-2026 Ford F-150 5.0L 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 while retaining the precise control needed for excellent street manners. Great linearity, superior short pulse width control, and tight manufacturing tolerances help deliver predictable fueling from idle and part throttle through higher-load operation, while plug-and-play connection to the OEM harness keeps installation straightforward.
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 is407-0525h is flow tested and rated at 43.5 PSI / 3 Bar and 90 degrees F fuel temperature using CF-16B calibration fluid. Plug-and-play Ford ECU data is also available from Fuel Injector Clinic to support accurate calibration, and the injectors include the O-rings required for the applicable factory configuration.

525cc Fueling for Whipple-Supercharged F-150 Performance
A Whipple-supercharged 5.0L moves substantially more air than a naturally aspirated combination, making accurate fuel delivery an important part of the overall setup. The FIC 525cc injector provides additional fueling capacity while maintaining the precise low-speed control needed for a street-driven truck. Its combination of 525cc/min flow, excellent linearity, and short pulse width repeatability gives your tuner a predictable foundation for managing fuel delivery throughout the operating range.
Precisely Flow Matched to Within 1%
Consistent fuel delivery across all eight cylinders is critical to a properly calibrated supercharged engine. Fuel Injector Clinic precisely flow matches each is407-0525h injector set to within 1%, helping minimize injector-to-injector variation. Every injector is individually numbered, and its individual results are documented on the detailed flow sheet included with the set. This provides valuable information for consistent cylinder-to-cylinder fueling and accurate tuning.
Built for Tunability and Drivability
Fuel Injector Clinic combines increased flow capacity with superior short pulse width control and tight manufacturing tolerances. These characteristics help the ECU accurately meter fuel during idle, cruising, and part-throttle operation while providing increased capacity as engine load rises. The result is a performance injector designed to deliver the additional fueling capability a modified combination needs without making drivability an afterthought.
Plug-and-Play OEM Harness Connection
The is407-0525h features plug-and-play connection to the OEM wiring harness, eliminating the need to cut, solder, or convert the factory injector wiring. Fuel Injector Clinic also supplies the O-rings required for the applicable factory configuration. Combined with available Ford ECU data, this application-ready design helps simplify installation and provides tuners with the information needed for calibration.
