Fuel Injector Clinic 2150cc BlueMax Fuel Injector (High-Z) Subaru WRX 2002-2014 / STI 2007-2021

Part #: ficIS175 - 2150H. This set includes 4 x 2150cc saturated/high - impedance fuel injectors from Fuel Injector Clinic, designed for Subaru WRX & STi ('07 & up), and fits '04 - '06 STi with WRX tumbler conversion. These are the largest high - impedance injectors available, using the latest injector technology and state - of - the - art Data Match Technology. No resistor pack or P&H drivers are needed. However, do not use with VP Import, Q16 or other MTBE oxygenated fuels. These injectors excel in low - end throttle response and short - pulse width control. The Data Match Technology used in production significantly improves the ECU's control in the sub 2ms pulse width area, common at idle and part - throttle. Each injector is individually serial - numbered, and detailed flow - matching and latency information is provided on the Data Match Sheet. They are flow - tested and rated at 43.5psi (3Bar) at 90°F fuel temperature with CF - 16B calibration fluid. Caution! The 2150cc/min injector's internal seal may swell when in contact with MTBE in oxygenated fuels, reducing flow. There are also potential corrosion issues with alcohol - based fuels like E85 during long - term disuse. All necessary o - rings for the factory application of the listed vehicle are included. For aftermarket or unusual setups, contact us before ordering. Our 12 - month warranty covers failure due to original manufacturing defects. These injectors are matched to the saturated injector signal of the vehicle's OEM ECU or suitable for high - impedance aftermarket ECUs.

Using these fuel injectors is straightforward. First, make sure you're using the right fuel. Avoid VP Import, Q16, and other MTBE oxygenated fuels as they can cause the internal seal to swell and reduce the injector's flow. For the listed vehicles, the injectors come with all the o - rings needed for a factory - fit installation. If you have an aftermarket or unusual setup, contact us to ensure you get the right fit. When it comes to maintenance, be aware that prolonged disuse while exposed to alcohol - based fuels like E85 can lead to corrosion. So, if you're not using the vehicle for a long time, it's a good idea to take steps to protect the injectors. Also, keep in mind that these injectors are covered by a 12 - month warranty against defects in original manufacture. If you experience any problems, reach out to us, and we'll take care of it.
