Fuel Injector Clinic 445cc Fuel Injector Set - High Z (is850-0445h) - Mini R52 / R53
Upgrade your Mini R52 or R53 fuel system with the Fuel Injector Clinic 445cc High-Z Fuel Injector Set. Part number is850-0445h includes four custom saturated, high-impedance ball and seat injectors engineered for excellent linearity, short pulse width repeatability, and consistent fuel delivery. For modified Mini builds that need additional fuel capacity beyond the factory injectors, this matched 445cc set delivers the precise control and predictable performance tuners need while helping maintain excellent drivability.
Fuel Injector Clinic precisely flow matches each injector set to within 1%. Every injector is individually numbered, with results for each injector supplied on the included detailed flow sheet. The injectors are flow tested and rated at 43.5 PSI, or 3 Bar, with fuel temperature at 90 degrees F using CF-16B calibration fluid. Tight manufacturing tolerances and superior short pulse width control help make these injectors straightforward to tune. PGTUSC4 solder-in pigtails are included for the required injector plug conversion, or optional PADPUtoJ4 plug-and-play adapters can be selected to avoid cutting or soldering the vehicle wiring harness.

Precision-Matched Fuel Delivery for Performance Mini Builds
A performance injector needs more than additional flow capacity. Consistency and controllability are critical to giving the ECU and tuner a predictable foundation for calibration. Fuel Injector Clinic's 445cc High-Z injectors combine increased fuel delivery with excellent linearity, tight manufacturing tolerances, and superior short pulse width control. Matching each four-injector set to within 1% helps promote consistent cylinder-to-cylinder fuel delivery while maintaining the control needed for responsive street drivability.
Part number is850-0445h requires an injector plug conversion when using the included PGTUSC4 pigtails. These pigtails can be soldered into the vehicle harness to replace the existing injector connectors. For a plug-and-play installation without cutting or soldering the factory harness, optional PADPUtoJ4 adapters are available. Fuel Injector Clinic also uses brand-new, unused injectors for its performance applications rather than remanufactured or core-program injectors. If your Mini uses an aftermarket fuel rail or another non-standard fuel-system configuration, contact Beefcake Racing before ordering to confirm proper fitment.

FAQs
Does the Fuel Injector Clinic is850-0445h injector set require wiring modifications?
Yes, when using the included PGTUSC4 pigtails, the existing injector plugs on the vehicle harness must be replaced. Optional PADPUtoJ4 plug-and-play adapters can be selected instead, allowing the injectors to connect without cutting or soldering the factory wiring harness.
How are the FIC is850-0445h 445cc injectors matched and tested?
Fuel Injector Clinic precisely flow matches each injector set to within 1%. Every injector is individually numbered, with its results provided on a detailed flow sheet included with the set. The injectors are flow tested and rated at 43.5 PSI, or 3 Bar, with fuel temperature at 90 degrees F using CF-16B calibration fluid.
