Fuel Injector Clinic 445cc Fuel Injector Set - High Z (is167-0445h) - 1997-2006 Volkswagen / Audi 4 Cylinder 53mm
Upgrade your Volkswagen or Audi four-cylinder fuel system with the precision and consistency of the Fuel Injector Clinic 445cc High-Z Fuel Injector Set. The is167-0445h includes four 445cc saturated, high-impedance ball-and-seat injectors in a 53mm configuration. Built for performance applications that need increased fueling with excellent control, these injectors combine strong linearity and short pulse width repeatability with tight manufacturing tolerances for predictable tuning and excellent drivability.
Fuel Injector Clinic precisely flow matches each is167-0445h injector set to within 1%. Every injector is individually numbered, and a detailed flow sheet showing the results for each injector is included with the set. FIC flow tests and rates these injectors at 43.5 PSI, or 3 Bar, at 90 degrees F fuel temperature using CF-16B calibration fluid. PGTUSC4 solder-in pigtails are included, while optional PADPUtoJ4 plug-and-play adapters provide an installation option without cutting or soldering the factory injector wiring. The injectors include 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.

Precisely Matched for Consistent Fuel Delivery
A performance injector needs to deliver more than additional fuel capacity. Consistency between injectors and accurate control at short pulse widths are critical to building a clean, responsive calibration. Fuel Injector Clinic precisely flow matches each is167-0445h set to within 1%, with every injector individually numbered and its results documented on the included flow sheet. Combined with excellent linearity, short pulse width repeatability, and tight manufacturing tolerances, this gives tuners a consistent foundation for dialing in a modified VW or Audi four-cylinder.
Wiring Options
The is167-0445h requires an injector plug conversion. PGTUSC4 pigtails are included and can be soldered into the vehicle wiring harness to replace the existing injector plugs. Optional PADPUtoJ4 plug-and-play adapters provide an alternative that connects the injectors to the existing harness without cutting or soldering. Fuel Injector Clinic uses brand-new, unused injectors for its performance applications rather than relying on remanufactured or core-program injectors.
