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

Part #: ficIS175 - 2150H. These Fuel Injector Clinic 2150cc saturated/high - impedance injectors are a great fit for Subaru WRX & STi ('07 and up), and can also work for '04 - '06 STi with WRX tumbler conversion. They're the largest high - impedance injectors out there! Using the latest injector tech and state - of - the - art Data Match Technology for perfect matching. No need for a resistor pack or P&H drivers. But don't use them with VP Import, Q16 or other MTBE oxygenated fuels. These injectors shine when you need great low - end throttle response and short pulse width control. Thanks to their large flow rate, the Data Match Technology dynamic flow matching used during production really boosts the ECU's control ability in the sub 2ms pulse width area, which is typical for idle and part - throttle. Each injector has a unique serial number, and the Data Match Sheet provides detailed flow matching and latency value info. They're flow - tested and rated at 43.5psi (3Bar) at 90°F fuel temperature with CF - 16B calibration fluid. Be careful! The 2150cc/min injector has a seal that swells when in contact with MTBE from oxygenated fuels, reducing flow. Also, there might be corrosion issues from long - term disuse with alcohol - based fuels like E85. These injectors come with all the o - rings for the factory application of the listed vehicle. For aftermarket or special setups, contact us before ordering. They're covered by a 12 - month warranty against manufacturing defects and are matched to the high - impedance injector signal from the vehicle's OEM ECU or aftermarket ECUs made for high - impedance injectors.

How to Use: These fuel injectors are designed to fit the factory application of the listed Subaru models. Just install them as you would with standard injectors, making sure to use the included o - rings. They're already matched to the high - impedance injector signal of the vehicle's OEM ECU or suitable for compatible aftermarket ECUs. Things to Note: Do not use these injectors with VP Import, Q16 or other MTBE oxygenated fuels as the internal seal may swell and reduce flow. If you plan to use alcohol - based fuels like E85, be aware of potential corrosion issues during long - term disuse. Maintenance Tips: Keep the injectors clean. If you don't use the vehicle for a long time, it's a good idea to check the injectors for any signs of corrosion, especially if you've used alcohol - based fuels. And if you're planning an aftermarket or non - standard setup, contact the seller before ordering to ensure a proper fit. These injectors are covered by a 12 - month warranty against manufacturing defects, so if you encounter any problems related to the original manufacture, reach out for support.
