Fuel Injector Clinic 525cc Fuel Injector Set - High Z (is140-0525h) - Scion tC / xB / Toyota 1ZZ
Upgrade your Scion or compatible Toyota fuel system with the Fuel Injector Clinic is140-0525h 525cc High-Z injector set. This matched set of four saturated, high-impedance ball and seat injectors provides increased fueling capacity along with the excellent linearity and short pulse width repeatability needed for accurate tuning and strong street drivability. For modified Scion tC, Scion xB, and compatible Toyota 1ZZ-powered applications that need more fuel than the factory injectors can provide, this set delivers a proven combination of performance, consistency, and control.
Fuel Injector Clinic precisely flow matches each injector set to within 1 percent, individually numbers each injector, and provides detailed flow results with the set. Every injector is flow tested and rated at 43.5 PSI (3 Bar) with fuel at 90 degrees F using CF-16B calibration fluid. Tight manufacturing tolerances and superior short pulse width control help make these injectors easier to calibrate while maintaining excellent drivability. PGTUSC4 solder-in pigtails are included, or optional PADPUtoT4 plug-and-play adapters can be added for installation without cutting or soldering the applicable factory harness.

Precisely Flow Matched for Consistent Performance
Increasing injector capacity is only part of building a properly functioning performance fuel system. Consistency between cylinders is equally important. Fuel Injector Clinic precisely flow matches the four injectors in each is140-0525h set to within 1 percent, helping provide balanced fuel delivery across the engine rather than relying on a collection of unmatched injectors.
Each injector is individually numbered, and detailed flow results are supplied with the set. Fuel Injector Clinic also tests and rates these injectors under controlled conditions at 43.5 PSI (3 Bar) and 90 degrees F using CF-16B calibration fluid. The result is a well-documented matched injector set that gives your tuner a consistent foundation for calibration.
525cc Performance With Excellent Drivability
The 525cc flow rate provides additional fueling capacity for modified applications while retaining the linearity and short pulse width control needed for smooth street operation. Precise control at shorter pulse widths is especially valuable during idle and part-throttle conditions, where an injector must consistently deliver very small amounts of fuel.
Fuel Injector Clinic combines this low pulse width control with tight manufacturing tolerances to help make the injectors easier to tune and provide excellent drivability. FIC also uses brand-new, unused injectors for its performance applications rather than relying on remanufactured injectors or core programs.
Wiring and Installation
The Fuel Injector Clinic is140-0525h set includes PGTUSC4 solder-in pigtails. Using the supplied pigtails requires replacing the applicable factory injector connectors and soldering the new connectors into the vehicle wiring harness. For owners who prefer to retain the applicable factory harness without cutting or soldering, optional PADPUtoT4 plug-and-play adapters are available.
Fuel Injector Clinic supplies the injectors with the O-rings required for the listed factory application. Vehicles equipped with aftermarket fuel rails or other unusual fuel-system configurations should be verified before ordering to ensure the correct injector setup is selected.
