Fuel Injector Clinic 2150cc Fuel Injector Set - High Z (is175-2150h) - 2002-2014 Subaru WRX / 2007-2021 STi
When a high-horsepower Subaru build demands serious fuel delivery without giving up the control needed for street manners and precise tuning, the Fuel Injector Clinic 2150cc High-Z Injector Set is built for the job. Designed for 2002-2014 Subaru WRX and 2007-2021 Subaru STi applications, this four-injector set combines massive 2150cc flow capability with saturated, high-impedance operation and Fuel Injector Clinic's advanced dynamic flow matching. The result is an injector package engineered to deliver the fuel capacity aggressive builds require while maintaining excellent short pulse width control for idle and part-throttle operation.
Fuel Injector Clinic uses its proprietary Data Match Technology to dynamically match these high-flow injectors, an especially important advantage with injectors of this size. This process improves the ECU's ability to control injector operation in the sub-2ms pulse width range commonly encountered during idle and part-throttle driving. Every injector is individually serial numbered, and the set includes a Data Match Sheet containing detailed flow matching and latency information. Injectors are flow tested and rated at 43.5 PSI, or 3 Bar, at 90 degrees F fuel temperature using CF-16B calibration fluid.

Important Fuel Compatibility Information
Do not use these injectors with VP Import, Q16, or other MTBE oxygenated fuels. The internal construction of the 2150cc injector contains a seal that can swell after exposure to MTBE. This can significantly reduce injector flow, making this injector unsuitable for MTBE oxygenated fuels. When using alcohol-based fuels such as E85, Fuel Injector Clinic's care instructions should be followed because prolonged disuse while the injectors remain exposed to alcohol-based fuel may create potential corrosion issues.

FAQs
Can Fuel Injector Clinic is175-2150h injectors be used with E85?
The manufacturer specifically discusses use with alcohol-based fuels such as E85, but proper care is important. Fuel Injector Clinic warns that prolonged disuse while the injectors are exposed to alcohol-based fuel can create potential corrosion concerns, so its injector care instructions should be followed.
Can these 2150cc injectors be used with Q16 or VP Import?
No. Fuel Injector Clinic specifically states that the is175-2150h 2150cc injectors 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.
