Fuel Injector Clinic 525cc Fuel Injector Set - High Z (is850-0525h) - Mini R52 / R53
Upgrade the fuel delivery capability of your Mini R52 or R53 with the Fuel Injector Clinic 525cc High-Z Fuel Injector Set. Part number is850-0525h includes four custom saturated, high-impedance ball and seat injectors engineered for excellent linearity, repeatable short pulse width performance, and consistent fuel delivery. For modified Mini builds that have outgrown the capacity of the factory fuel injectors, this matched 525cc set provides increased fueling capability while retaining the precise control needed for responsive drivability and accurate tuning.
Fuel Injector Clinic precisely flow matches each injector set to within 1%, with every injector individually numbered and its results supplied on a 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 while supporting excellent drivability. PGTUSC4 solder-in pigtails are included for the required injector plug conversion, or optional PADPUtoJ4 plug-and-play adapters can be selected for installation without cutting or soldering the vehicle wiring harness.

Matched Fuel Delivery for Performance Mini Builds
More injector capacity only helps when the ECU can accurately control the additional fuel. Fuel Injector Clinic's 525cc High-Z injectors combine increased flow with excellent linearity, tight manufacturing tolerances, and superior short pulse width control. Each four-injector set is precisely flow matched to within 1%, helping provide consistent cylinder-to-cylinder fuel delivery and giving tuners a predictable foundation for proper calibration.
Part number is850-0525h requires an injector plug conversion. The included PGTUSC4 pigtails can be soldered into the vehicle harness to replace the existing injector connectors. For owners who prefer to retain the factory harness without cutting or soldering, optional PADPUtoJ4 plug-and-play adapters provide an alternative installation solution. FIC uses brand-new, unused injectors for its performance applications rather than relying on 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 is850-0525h 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 is850-0525h 525cc injectors matched and tested?
Fuel Injector Clinic precisely flow matches each injector set to within 1%. Every injector is individually numbered, and its results are 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.
