Fuel Injector Clinic 850cc Fuel Injector Set - High Z (is144-0850h) - 2013-2016 Scion FR-S
Give your 2013-2016 Scion FR-S the additional fuel capacity needed for a serious performance build with the Fuel Injector Clinic is144-0850h 850cc High-Z fuel injector set. Previously offered as the is144-0770H 770cc set, this current 850cc version includes four saturated, high-impedance ball and seat injectors engineered for excellent linearity, short pulse width repeatability, and predictable fuel delivery. The result is a performance injector set that provides substantially increased fueling capability while retaining the precise control needed for accurate tuning and strong drivability.
Fuel Injector Clinic precisely matches the is144-0850h set using its proprietary Data Match Technology. Each injector is individually serial numbered, with detailed flow matching and latency information supplied on the included Data Match Sheet. The injectors are flow tested and rated at 43.5 PSI (3 Bar) with fuel at 90 degrees F using CF-16B calibration fluid. PGTUSC4 solder-in pigtails are included, while optional PADPUtoD4 plug-and-play adapters provide an installation option that eliminates the need to cut or solder the factory wiring harness.

850cc Fueling With Precise Low-Pulse Control
A performance injector needs to do more than deliver additional fuel at wide-open throttle. It also needs predictable operation at the shorter pulse widths encountered during idle and part-throttle driving. The Fuel Injector Clinic is144-0850h combines 850cc/min flow capacity with excellent linearity, short pulse width repeatability, and precise matching. This gives the ECU and tuner consistent injector behavior across a broad operating range, making the set a strong choice for modified FR-S applications that need more fuel without treating drivability as an afterthought.
Data Match Technology
Fuel Injector Clinic uses its proprietary Data Match Technology to precisely match the injectors within each is144-0850h set. Every injector is individually serial numbered, and its results are documented on the supplied Data Match Sheet with detailed flow matching and latency information. Providing accurate injector data gives your tuner better information for calibration and helps promote consistent fuel delivery across all four cylinders.
Controlled Flow Testing
Fuel Injector Clinic flow tests and rates these injectors at 43.5 PSI (3 Bar) with fuel maintained at 90 degrees F using CF-16B calibration fluid. Combined with precise matching, superior short pulse width control, and tight manufacturing tolerances, this controlled testing helps provide the predictable injector performance needed for accurate calibration and dependable drivability.
Injector Plug Conversion
The is144-0850h requires an injector connector conversion when installed with the factory wiring harness. Fuel Injector Clinic includes PGTUSC4 solder-in pigtails that can be used to replace the original injector connectors. If you prefer not to cut or solder the factory harness, optional PADPUtoD4 plug-and-play adapters provide a straightforward alternative.
Fuel Injector Clinic uses brand-new, unused injectors for its performance applications rather than relying on remanufactured or core-program injectors. The set is also configured with the O-rings required for the listed factory application. If your FR-S uses an aftermarket fuel system or another unusual configuration, contact Beefcake Racing before ordering to verify the correct injector setup for your combination.

FAQs
Is the is144-0850h the replacement for Fuel Injector Clinic's previous 770cc FR-S injector set?
Yes. Fuel Injector Clinic identifies the current is144-0850h 850cc injector set as the replacement for the previous is144-0770H part number. The current set is rated at 850cc/min.
Do the is144-0850h injectors require modifying the FR-S wiring harness?
The included PGTUSC4 pigtails require the original injector connectors to be replaced by soldering in the supplied pigtails. Optional PADPUtoD4 plug-and-play adapters can instead connect the injectors to the factory harness without cutting or soldering.
