WRX 02-14 & STi 07-20 | ID2600-XDS | Injector Dynamics | 2600.48.11.WRX.4
ID2600-XDS, for WRX 02-14 & STi 07-20/ Turbo 2.0L & 2.5L. WRX-16B bottom adapters. 11mm (red) adapters
The ID2600-XDS is the most recent offering from the partnership of Injector Dynamics and Bosch Motorsport.
The ID2600-XDS was developed specifically for use with liquid fuels, featuring corrosion resistant internals, and long term compatibility with ethanol and methanol.
The ID2600-XDS has the highest flow rate of any injector offered by Bosch, and flows 50% more than the ID1700x.
The ID2600-XDS benefits from Dual Slope Matching, a method of matching the flow rate in both the linear, and nonlinear operating range, providing better cylinder to cylinder consistency at low pulse widths.
Basic Specifications
- Nominal Flow Rate – 2600cc/min @ 3.0 Bar (43.5 psi)
- Maximum Differential Fuel Pressure – 9.0 Bar (130.5 psi) – Requires Minimum 11volt.
- Fuel Compatibility – Compatible with Methanol/Ethanol/All Known Hydrocarbons. NOT Compatible with Ethers (MTBE, ETBE, TAME) or Nitro Methane
- Electrical Connector – USCAR

What is Dual Slope Matching?
Dual Slope Matching is a method of matching injectors that provides the best possible cylinder to cylinder fueling across the entire operating range.
Traditionally, injectors were matched based on static flow rate alone, which resulted in large deviations at low pulse widths.
Injector Dynamics introduced Slope Intercept Matching over a decade ago, which provided even cylinder to cylinder fueling across the linear operating range of the injector.
With the progression of turbo technology, and increased use of alcohol fuels, greater demands are placed on fuel injectors, and they are often required to deliver fuel well outside of their linear operating range.
The concept of Dual Slope Matching extends the injector matching into the lower non linear operating range. Dual Slope Matching was conceived by Aaron Looft of Injector Dynamics, who was inspired by the dual slope injector characterization model used by Ford.

Frequently Asked Questions About the WRX 02-14 & STi 07-20 ID2600-XDS Injectors
What makes the Injector Dynamics ID2600-XDS a good upgrade for WRX 02-14 and STi 07-20 models?
The Injector Dynamics ID2600-XDS injectors provide exceptional fuel flow, reliability, and tuning precision, making them an ideal upgrade for WRX 02-14 and STi 07-20 vehicles. Their advanced XDS technology ensures consistent performance for high-boost and high-horsepower setups.
Are the ID2600-XDS injectors plug-and-play for Subaru WRX and STi models?
The injectors physically fit the WRX 02-14 and STi 07-20 models, but proper ECU tuning is required after installation. With the correct tune, they integrate seamlessly into both stock and modified fuel systems.
Can the Injector Dynamics ID2600-XDS injectors run E85 on a WRX or STi?
Yes, the ID2600-XDS injectors are fully compatible with E85 and other ethanol-based fuels. Their corrosion-resistant materials and precise flow control make them perfect for Subaru owners running high-ethanol or flex-fuel builds.
How much horsepower can the ID2600-XDS injectors support on a WRX or STi?
With the proper supporting modifications and tuning, the ID2600-XDS injectors can support extremely high horsepower builds, often exceeding 600+ wheel horsepower in turbocharged Subaru applications.
Do I need additional fuel system upgrades when installing the ID2600-XDS injectors?
While the injectors themselves provide excellent flow capacity, many WRX and STi setups benefit from upgraded fuel pumps, fuel rails, and lines—especially when targeting high horsepower or running E85. These upgrades help maintain consistent fuel pressure and performance.
