Fuel Injector Clinic 445cc Injector Set (is407-0445h) - 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 445cc injector set. This matched set of eight high-impedance injectors flows 445cc/min, or 42 lbs/hr, at 43.5 PSI fuel pressure, providing increased fuel capacity for a modified Coyote combination 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 individual results documented on the detailed flow sheet included with the set. The is407-0445h 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.

445cc Fueling for Whipple-Supercharged F-150 Performance
A Whipple-supercharged 5.0L requires accurate fuel delivery as airflow and engine load increase. The FIC 445cc injector provides additional fueling capacity while retaining the precise low-speed behavior needed for a street-driven performance truck. Its combination of 445cc/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 is407-0445h 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 provides useful injector-specific information for consistent cylinder-to-cylinder fueling and accurate calibration.
Built for Tunability and Drivability
Increasing injector capacity should not mean sacrificing low-speed fuel control. Fuel Injector Clinic combines excellent linearity, superior short pulse width control, and tight manufacturing tolerances to help the ECU accurately meter fuel during idle, cruising, and part-throttle operation. As engine load increases, the additional injector capacity provides the fuel delivery needed to support the modified combination.
Plug-and-Play OEM Harness Connection
The is407-0445h 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.
