Injector Dynamics - ID1700X Injectors (Set of 4) Top Feed Conversion Kit - Subaru STi 04-06 

The ID1700X Injectors (Set of 4) from Injector Dynamics and Bosch Motorsport is the latest collaboration that aims to bridge the gap between the ID1300x and the ID2000. With corrosion-resistant internals, this injector is suitable for use with all automotive fuels.

The ID1700X offers a specialized magnetic circuit, developed through extensive research, that eliminates issues with voltage and pressure sensitivity commonly found in other high impedance, high flow injectors. This injector performs exceptionally well under high pressures often seen in modern automotive systems and is reliable in all related applications.

The ID1700X is a highly versatile injector that can handle all types of fuel and deliver high flow rates. It is commonly used for delivering E85 to boosted engines and occasionally for gasoline in high horsepower applications. Its design prioritizes high flow rates over low flow rate linearity for these specific applications.

The ID1700x will deliver flawless stoichiometric idle and cruise mixtures on E85, but like the ID2000, should not be expected to do so on gasoline.

If you need flawless drivability on gasoline, the ID1300x will provide this, and is capable of approximately 150hp per injector on E85.

Nominal Flow Rate – 1725cc/min @ 3.0 Bar (43.5 psi) Using Iso-Octane at 52 Degrees C (125 Degrees F)
Maximum Differential Fuel Pressure – 7.0 Bar (101.5 psi)
Fuel Compatibility – Compatible with Methanol/Ethanol/All Known Hydrocarbon Fuels.
Electrical Connector – USCAR



Are you tired of pouring over logs, making corresponding changes to your tune, only to find that what worked one day is off by the next? Have you wasted hours sifting through a myriad of injector related forum posts, only to find that there is no simple solution? Such is the nature of tuning with inaccurate injector data.


Accurate injector characterizations are the basis of all fueling calculations, so it’s no wonder that if you’re tuning without them, you will spend a lot of valuable time making the best of a bad situation. It will keep you busy searching for endless combinations of mostly incorrect answers, and it will rob you of the most basic functions provided by the guys who spent millions of R&D dollars designing the engine management system for your car.

Whether you are a professional tuner, or an end user, you can spend countless hours getting it “mostly correct” or you can copy and paste accurate characterization tables and get on with the job of maximizing performance and drivability.

Injector Dynamics is the only motorsport injector supplier capable of generating these OEM quality injector characterizations, and our engineering services are available to generate data for new platforms and applications at no cost to our customers.


We welcome the opportunity to provide solutions where none previously existed, and it is this commitment to value and innovation that has earned us our position as the industry leader.

Remember that next time you hear “The Same as Injector Dynamics but Cheaper”
