Fuel Injector Clinic 2150cc Fuel Injector Set - High Z (is165-2150h) - 1988-1998 Volkswagen / Audi 4 Cylinder 64mm
Take your high-horsepower Volkswagen or Audi fuel system to the next level with the Fuel Injector Clinic 2150cc High-Z Fuel Injector Set. Designed for compatible 1988-1998 VW/Audi four-cylinder applications using the 64mm injector configuration, the is165-2150h includes four massive 2150cc saturated, high-impedance injectors. Despite their extreme flow capacity, these injectors are engineered for excellent low-end throttle response and precise short pulse width control, giving serious performance builds the fuel delivery they need without sacrificing the control required at idle and part throttle.
Fuel Injector Clinic uses proprietary Data Match Technology with dynamic flow matching to precisely characterize these high-flow injectors. 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 PGTDEN4 solder-in pigtails, while optional PADPDtoJ4 plug-and-play adapters allow connection 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.

Massive Fuel Capacity with Precise Low-Pulse Control
The challenge with an injector this large is not simply delivering enough fuel at wide-open throttle. Controlling that fuel accurately at idle and part throttle is just as important. Fuel Injector Clinic uses dynamic Data Match Technology during production of the 2150cc set because of its exceptionally high flow rate. This improves the ECU's ability to control the injectors in the sub-2ms pulse width range commonly encountered during idle and part-throttle operation, helping deliver the response and drivability demanded from a properly tuned high-horsepower combination.
Important Fuel Compatibility Warning
Do not use the is165-2150h with VP Import, Q16, or other MTBE oxygenated fuels. The internal construction of the 2150cc injector contains a seal that can swell when exposed to MTBE. This swelling can significantly reduce injector flow, making the injector unsuitable for MTBE oxygenated fuels. When using alcohol-based fuels such as E85, follow Fuel Injector Clinic's care instructions because prolonged disuse while the injectors remain exposed to alcohol-based fuel can create potential corrosion concerns.
Wiring Options
The is165-2150h requires an injector plug conversion. PGTDEN4 pigtails are included and can be soldered into the vehicle wiring harness to replace the existing injector plugs. Optional PADPDtoJ4 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.

FAQs
Can I use the Fuel Injector Clinic is165-2150h with Q16 or VP Import?
No. Fuel Injector Clinic specifically states that the 2150cc injector must not be used with VP Import, Q16, or other MTBE oxygenated fuels. MTBE can cause an internal seal to swell, significantly reducing injector flow.
Does the is165-2150h require an injector plug conversion?
Yes. PGTDEN4 solder-in pigtails are included with the injector set. Optional PADPDtoJ4 plug-and-play adapters can be used instead if you want to connect the injectors without cutting or soldering the factory injector wiring.
Why Buy Fuel Injector Clinic Injectors From Beefcake Racing?
Beefcake Racing can help you choose the correct Fuel Injector Clinic injectors and supporting fuel-system components for your Volkswagen or Audi performance build. With an injector as large as the is165-2150h, proper injector sizing, fuel selection, tuning, and supporting fuel-system capacity are critical.
