Fuel Injector Clinic 2150cc Fuel Injector Set - High Z (is176-2150h) - 2004-2006 Subaru STI / 2005-2006 Legacy GT
Feed a serious high-horsepower Subaru build with the massive fuel capacity and precise low-pulse-width control of the Fuel Injector Clinic is176-2150h 2150cc High-Z fuel injector set. Designed for 2004-2006 Subaru STI and 2005-2006 Legacy GT applications using the required top-feed conversion, this four-injector set combines enormous 2150cc/min flow capacity with saturated, high-impedance operation and Fuel Injector Clinic's proprietary Data Match Technology. These injectors are an excellent option for high-volume fuels such as E85, while FIC's dynamic matching helps maintain the control required at idle and part throttle despite the exceptionally high flow rate.
Important fitment note: The is176-2150h injector set only fits the original tumblers when used with the FIC RL STi top-feed fuel rail conversion. Verify that your vehicle has the required FIC top-feed conversion before ordering.
Because of the exceptionally high flow rate, FIC uses dynamic Data Match Technology during production to improve ECU control in the sub-2ms pulse width range commonly encountered during idle and part-throttle operation. Every injector is individually serial numbered, and the included Data Match Sheet provides detailed flow matching and latency information. These injectors are flow tested and rated at 43.5 PSI (3 Bar) with fuel at 90 degrees F using CF-16B calibration fluid.

Massive Fuel Delivery With Precise Low-Pulse-Width Control
Moving enough fuel for a serious horsepower combination is only part of the equation. The ECU still needs to control the injector accurately when fuel demand drops at idle and part throttle. That challenge becomes increasingly important as injector size grows, which is why Fuel Injector Clinic applies dynamic flow matching to the 2150cc set.
Data Match Technology significantly improves the ECU's ability to control these injectors in the sub-2ms pulse width range. The result is an injector engineered to deliver the massive flow demanded by high-output combinations while retaining the low-pulse-width behavior necessary for tuning and drivability.
Fuel Injector Clinic Data Match Technology
Every is176-2150h injector is individually serial numbered and matched using Fuel Injector Clinic's proprietary Data Match Technology. The results are supplied on the included Data Match Sheet, providing detailed flow matching and latency information that gives the tuner accurate data for calibration.
Fuel Injector Clinic flow tests and rates these injectors at 43.5 PSI (3 Bar) with fuel at 90 degrees F using CF-16B calibration fluid. The combination of controlled testing, dynamic matching, and detailed injector data provides a strong foundation for accurately calibrating a high-output Subaru fuel system.
Important Fuel Compatibility Information
Do not use the is176-2150h 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.
The 2150cc injector can be used with alcohol-based fuels such as E85, but FIC's care instructions should be followed. Prolonged disuse while the injectors remain exposed to alcohol-based fuel can create potential corrosion issues, making proper fuel-system care especially important on vehicles that may sit for extended periods.
Installation and Fitment Note
The is176-2150h is designed specifically for top-feed-converted 2004-2006 Subaru STI and 2005-2006 Legacy GT applications. These injectors only fit the original tumblers when used with the FIC RL STi top-feed fuel rail conversion. They should not be treated as a direct replacement for a vehicle that has not received the required top-feed conversion.
Fuel Injector Clinic supplies the injectors with the O-rings required for the listed application. If your Subaru uses aftermarket components or another unusual fuel-system configuration, verify injector fitment before ordering to ensure the injectors are correct for your setup.

FAQs
Can the Fuel Injector Clinic is176-2150h injectors be used with E85?
Yes. The 2150cc injectors are well suited to the high fuel-volume demands of E85 applications. However, they must not be used with VP Import, Q16, or other MTBE-oxygenated fuels, and FIC's care instructions should be followed when using alcohol-based fuels.
Will the is176-2150h injectors fit a stock 2004-2006 Subaru STI or 2005-2006 Legacy GT fuel system?
No. This injector set only fits the original tumblers when used with the FIC RL STi top-feed fuel rail conversion. Verify that your vehicle has the required top-feed conversion before ordering.
