Fuel Injector Clinic 650cc Fuel Injector Set - High Z (is167-0650h) - 1997-2006 Volkswagen / Audi 4 Cylinder 53mm
Upgrade your performance Volkswagen or Audi four-cylinder with the Fuel Injector Clinic 650cc High-Z Fuel Injector Set. The is167-0650h includes four 650cc saturated, high-impedance ball-and-seat injectors in a 53mm configuration. Designed to provide increased fuel capacity while retaining excellent control at lower pulse widths, these injectors deliver the linearity, repeatability, and drivability needed for a properly tuned street or performance build.
Fuel Injector Clinic precisely matches the is167-0650h set using its proprietary Data Match Technology. Each injector is individually serial numbered, and the included Data Match Sheet provides detailed flow matching and latency information for accurate ECU calibration. 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. The set includes PGTUSC4 solder-in pigtails, while optional PADPUtoJ4 plug-and-play adapters provide an installation option without cutting or soldering the factory injector wiring. Required O-rings for the listed factory application are included, and every injector is backed by Fuel Injector Clinic's lifetime warranty against failure caused by defects in original manufacture.

650cc Performance with Data Matched Precision
A performance injector needs more than additional flow capacity. Consistent fuel delivery throughout the operating range is critical to both tuning and drivability. Fuel Injector Clinic combines the 650cc/min capacity of the is167-0650h with excellent linearity, short pulse width repeatability, and precise Data Match Technology. The result is a matched injector set designed to provide predictable fueling from idle and part-throttle operation through higher-load performance driving.
Wiring Options
The is167-0650h requires an injector plug conversion. PGTUSC4 pigtails are included and can be soldered into the vehicle wiring harness to replace the existing injector plugs. For an installation that does not require cutting or soldering the factory harness, optional PADPUtoJ4 plug-and-play adapters connect the injectors to the existing wiring. FIC uses brand-new, unused injectors for its performance applications rather than relying on remanufactured or core-program injectors.
