Fuel Injector Clinic 1650cc Fuel Injector Set - High Z (is165-1650h) - 1988-1998 Volkswagen / Audi 4 Cylinder 64mm
Feed a serious Volkswagen or Audi performance build with the Fuel Injector Clinic 1650cc High-Z Fuel Injector Set. Designed for 1988-1998 VW/Audi four-cylinder applications using the 64mm injector configuration, the is165-1650h includes four 1650cc saturated, high-impedance ball-and-seat injectors. This high-flow set combines the fuel capacity needed for demanding horsepower combinations with excellent idle performance, short pulse width control, and the drivability needed for a properly tuned street car.
The 1650cc injector uses stainless alloy valve construction and is compatible with pump gasoline, E85, Q16, VP Import, FTW, and other MTBE oxygenated race fuels. Fuel Injector Clinic precisely matches each set using proprietary Data Match Technology, individually serial numbers every injector, and supplies a Data Match Sheet containing detailed flow matching and latency information. These injectors are flow tested and rated at 43.5 PSI, or 3 Bar, at 90 degrees F fuel temperature using CF-16B calibration fluid. They are configured for plug-and-play connection to the OEM harness, 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.

High-Flow Fueling Without Sacrificing Drivability
Large injectors need more than raw flow capacity to work well in a street-driven performance car. Fuel Injector Clinic engineered the 1650cc High-Z injector to deliver the fuel volume required for serious horsepower while retaining excellent idle characteristics and precise short pulse width control. That combination makes the is165-1650h well suited to builds that need substantial fueling headroom on gasoline, E85, or compatible race fuels without giving up the control required during idle and part-throttle operation.
Data Match Technology
Fuel Injector Clinic uses its proprietary Data Match Technology to precisely match the injectors within each set. Every injector is individually serial numbered, and the supplied Data Match Sheet provides detailed flow matching and latency information. Accurate injector characterization gives your tuner better data to work with and helps the ECU deliver consistent fueling across all four cylinders.
Plug-and-Play OEM Harness Connection
Unlike FIC applications that require solder-in pigtails or separate plug adapters, the is165-1650h is configured for plug-and-play connection to the OEM injector harness. This eliminates the injector plug conversion required with some other high-flow injector sets while retaining the performance advantages of a 1650cc High-Z injector.
