Fuel Injector Clinic 1200cc (Previously 1100cc) Fuel Injector Set - High Z (is850-1200h) - Mini R52 / R53
Upgrade your Mini R52 or R53 with the Fuel Injector Clinic 1200cc High-Z Fuel Injector Set, a high-flow solution engineered for serious performance without sacrificing the precise fuel control needed for street drivability. Part number is850-1200h includes four custom saturated, high-impedance ball and seat injectors with excellent linearity and short pulse width repeatability. Previously offered as IS850-1100H, this updated 1200cc set provides substantial fueling capacity for modified and high-output Mini builds while retaining the response and consistency tuners need for accurate calibration.
Fuel Injector Clinic precisely matches each four-injector set using its proprietary Data Match Technology. Every injector is individually serial numbered, and detailed flow matching and latency information is supplied on the included Data Match 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. Superior short pulse width control and precise matching help deliver excellent drivability when properly calibrated, while the application-specific plug-and-play connection to the OEM harness simplifies installation by eliminating the need for an injector plug conversion.

High-Flow Performance with Plug-and-Play Installation
Large injectors need more than raw fuel capacity to perform well in a street-driven car. Fuel Injector Clinic's 1200cc High-Z injectors combine substantial flow capability with superior short pulse width control and precise matching, helping the ECU accurately meter fuel during idle, part-throttle, and high-load operation. For a properly calibrated R52 or R53, that balance provides the fueling headroom required by serious performance combinations while maintaining the control needed for responsive drivability.
The application-specific is850-1200h configuration also offers a major installation advantage. These injectors are designed to connect directly to the OEM Mini injector harness, eliminating the need to splice replacement pigtails into the factory wiring or add plug conversion adapters. All O-rings required for the listed factory application are included. If your Mini uses an aftermarket fuel rail or another non-standard fuel-system configuration, contact Beefcake Racing before ordering to verify proper injector fitment.

FAQs
Is the Fuel Injector Clinic is850-1200h the injector set previously sold as IS850-1100H?
Yes. Fuel Injector Clinic identifies the is850-1200h as the current 1200cc High-Z injector set that was previously offered as IS850-1100H. It includes four injectors specifically configured for Mini R52 and R53 applications.
Does the FIC is850-1200h require an injector plug conversion?
No. The is850-1200h is designed as a plug-and-play fit to the OEM Mini injector harness, so replacement injector pigtails or plug conversion adapters are not required for the factory wiring configuration.
