Fuel Injector Clinic 525cc Fuel Injector Set - High Z (1993 - 1998 Volkswagen / Audi - 6 Cylinder - 64mm) IS166-0525H
Upgrade your 1993-1998 Volkswagen or Audi six-cylinder fuel system with the Fuel Injector Clinic 525cc High-Z Fuel Injector Set. Designed for applications requiring a 64mm injector, the IS166-0525H set includes six saturated/high impedance ball and seat injectors engineered for excellent linearity, consistent short pulse width operation, and dependable drivability. Tight manufacturing tolerances and precise flow matching give tuners a predictable foundation for calibration while delivering the fuel control expected from a purpose-built performance injector.
Fuel Injector Clinic precisely flow matches each IS166-0525H injector set to within 1 percent. Every injector is individually numbered, with its results documented on the detailed flow sheet supplied with the set. FIC flow tests and rates these injectors at 43.5 PSI (3 Bar) with fuel at 90 degrees F using CF-16B calibration fluid. The injectors come configured with the O-rings required for the listed factory application and are backed by Fuel Injector Clinic's lifetime warranty against failure caused by defects in original manufacture.

Wiring and Installation
The IS166-0525H injector set requires an injector plug conversion when installed with the factory wiring harness. Fuel Injector Clinic includes PGTUSC6 pigtails that can be soldered into the vehicle harness to replace the existing injector plugs. For an installation that does not require cutting or soldering the factory harness, optional PADPUtoJ6 plug-and-play adapters can be added to connect the injectors to the existing wiring.
Fuel Injector Clinic chooses brand-new, unused injectors for its performance applications rather than relying on remanufactured or core-program injectors. The set is supplied with the O-rings required for the listed factory application. If your vehicle uses an aftermarket fuel rail or another non-standard fuel system configuration, injector compatibility should be verified before ordering.
