Fuel Injector Clinic 1000cc Fuel Injector Set - High Z (is177-1000h) - 2013-2020 Subaru BRZ
Upgrade the fuel system in your 2013-2020 Subaru BRZ with the proven flow capacity and precise control of the Fuel Injector Clinic is177-1000h 1000cc High-Z fuel injector set. This four-injector package uses saturated, high-impedance Ball & Seat injectors engineered for excellent linearity, consistent short pulse width operation, and the fuel delivery required by modified BRZ combinations. Whether you are building a responsive street car or increasing the fuel demands of a more serious performance setup, these FIC injectors provide a strong balance of increased capacity and tunability.
Fuel Injector Clinic precisely flow matches each injector set to within 1 percent, individually numbers every injector, and supplies detailed flow results with the set. The injectors are flow tested and rated at 43.5 PSI (3 Bar) with fuel at 90 degrees F using CF-16B calibration fluid. The is177-1000h includes PGTUSC4 solder-in pigtails, while optional PADPUtoD4 plug-and-play adapters allow installation without cutting or soldering the factory injector wiring.

1000cc Fueling for Modified Subaru BRZ Builds
As horsepower increases, the factory fuel system can become a limiting factor. The FIC is177-1000h gives modified BRZ applications substantially increased injector capacity while maintaining the precise low-pulse-width operation needed for good drivability. Excellent linearity and repeatable injector behavior help give the tuner predictable fuel delivery instead of simply adding flow capacity at the expense of control.
That combination makes the 1000cc High-Z set a versatile upgrade for performance-focused BRZ builds. Tight manufacturing tolerances and precise flow matching help each cylinder receive consistent fueling, while the high-impedance design provides the control needed for a properly calibrated street or performance application.
Precisely Flow Matched
Fuel Injector Clinic precisely flow matches each high-performance injector set to within 1 percent. Every injector in the is177-1000h set is individually numbered, and detailed flow results are supplied with the injectors. Matching the injectors as a complete set gives the tuner a more consistent foundation for calibration and helps support balanced fuel delivery across all four cylinders.
FIC flow tests and rates these injectors at 43.5 PSI (3 Bar) with fuel at 90 degrees F using CF-16B calibration fluid. Superior short pulse width control and tight manufacturing tolerances further contribute to predictable injector behavior, easier tuning, and strong drivability.
Wiring and Installation
The is177-1000h requires an injector plug conversion when connecting to the factory Subaru BRZ wiring harness. Fuel Injector Clinic includes four PGTUSC4 pigtails that can be soldered into the vehicle harness to replace the original injector connectors. For owners who do not want to cut or solder the factory harness, optional PADPUtoD4 plug-and-play adapters can be used instead.
Fuel Injector Clinic chooses brand-new, unused injectors for its performance applications rather than relying on remanufactured or core-program injectors. The injectors are supplied with the O-rings required for the listed factory application. Vehicles equipped with aftermarket fuel rails or other nonstandard fuel-system configurations should have injector fitment verified before ordering.

FAQs
What makes the Fuel Injector Clinic is177-1000h a good upgrade for a modified Subaru BRZ?
The is177-1000h combines 1000cc/min fuel capacity with high-impedance operation, excellent linearity, precise flow matching, and strong short pulse width repeatability. This gives tuners increased fueling capability while maintaining the control needed for good idle, part-throttle operation, and overall drivability.
Do the is177-1000h injectors plug directly into the factory Subaru BRZ wiring harness?
No. The set includes PGTUSC4 solder-in pigtails for converting the injector connections. Optional PADPUtoD4 plug-and-play adapters can be purchased to connect the injectors to the factory harness without cutting or soldering.
