Fuel Injector Clinic 525cc Fuel Injector Set - High Z (is165-0525h) - 1988-1998 Volkswagen / Audi 4 Cylinder 64mm
Upgrade your performance Volkswagen or Audi with the Fuel Injector Clinic 525cc High-Z Fuel Injector Set. Designed for compatible 1988-1998 VW/Audi four-cylinder applications using the 64mm injector configuration, the is165-0525h includes four 525cc saturated, high-impedance ball-and-seat injectors. Excellent linearity, short pulse width repeatability, and tight manufacturing tolerances provide the precise fuel control needed for responsive tuning, strong drivability, and consistent performance throughout the operating range.
Fuel Injector Clinic precisely flow matches each is165-0525h injector set to within 1%. Every injector is individually numbered, with individual results supplied on the detailed flow sheet 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 a no-cut, no-solder connection option. The injectors are supplied 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.

Precise Fuel Control for Performance VW and Audi Builds
Injector performance is about more than flow capacity. Consistency between cylinders, predictable operation at short pulse widths, and accurate characterization all matter when dialing in a performance calibration. Fuel Injector Clinic combines the 525cc/min capacity of the is165-0525h with tight manufacturing tolerances, excellent linearity, and precise flow matching within 1%. The result is a matched injector set designed to give the tuner consistent fuel delivery from idle and part throttle through higher-load operation.
Wiring Options
The is165-0525h 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.
