Fuel Injector Clinic 775cc Fuel Injector Set - High Z (is167-0775h) - 1997-2006 Volkswagen / Audi 4 Cylinder 53mm
Upgrade the fuel system on your performance Volkswagen or Audi four-cylinder with the Fuel Injector Clinic 775cc High-Z Fuel Injector Set. The is167-0775h includes four 775cc saturated, high-impedance ball-and-seat injectors in a 53mm configuration. Designed for modified VW and Audi applications that need more fuel capacity without sacrificing precise low-load control, these injectors deliver excellent linearity, short pulse width repeatability, and the predictable performance tuners need for a responsive, well-mannered combination.
Fuel Injector Clinic precisely matches the is167-0775h 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 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 pigtails, with optional PADPUtoJ4 plug-and-play adapters available to eliminate the need to cut or solder 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.

Precise Fuel Delivery for Performance VW and Audi Builds
More injector capacity is only useful when the ECU can control it accurately. Fuel Injector Clinic combines the 775cc/min flow capacity of the is167-0775h with excellent linearity, short pulse width repeatability, and precise Data Match Technology. Each injector is individually serial numbered and supplied with detailed flow matching and latency information, giving tuners the consistency and injector data needed to build a responsive calibration across idle, part-throttle, and high-load operation.
Wiring Options
The is167-0775h injector set 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. FIC uses brand-new, unused injectors for its performance applications rather than relying on remanufactured or core-program injectors.
