Injector Dynamics ID1750-XDS Fuel Injectors | Set of 4 | Subaru 2002-2014 WRX & 2007-2020 STi / Legacy GT / 2007-2013 Forester XT (1750.48.11.WRX.4)

Big injectors do not have to mean a lumpy idle and ugly cold starts.

Once boost and ethanol enter the picture, factory injectors become the first hard ceiling in the whole combination. The ID1750-XDS (the current evolution of the ID1750x) answers that with 1728cc/min of flow at 3.0 bar, compatibility with methanol, ethanol, and all known hydrocarbon fuels, delivered as a matched set of 4 for your Subaru 2002-2014 WRX & 2007-2020 STi / Legacy GT / 2007-2013 Forester XT. Each set is flow matched using Dual Slope Matching and backed by full characterization data, so your ECU gets real numbers, not estimates. Fueling you can build a tune on.

What You'll Feel

• Crisp part-throttle response instead of the surge and stumble big injectors are known for
• Stock-like idle and clean cold starts, even at this injector size
• Faster dyno sessions, because accurate injector data means less time chasing fuel trims
• Cylinder-to-cylinder consistency you can see in your lambda and EGT logs
• Confidence to run ethanol daily without worrying what it is doing to your injectors

Features

• Nominal flow rate: 1728cc/min at 3.0 bar (43.5 psi), measured with E10 fuel at 49 degrees C
• Maximum differential fuel pressure: 7.0 bar (101.5 psi)
• Compatible with methanol, ethanol, MTBE, nitromethane, and all known hydrocarbon fuels
• USCAR electrical connector
• Configuration: 48mm body, 11mm adapter top, WRX 16B bottom adapter (Subaru side feed conversion)
• Supplied as a flow-matched set with Dual Slope Matching for consistent delivery at low pulse widths
• Corrosion resistant construction for long service life on alcohol fuels

The Details

The ID1750-XDS sits between the 1300 and 2600 in the XDS lineup, sized for serious ethanol and methanol builds that have outgrown the 1300 class. Dual Slope Matching matches flow in both the linear and nonlinear range, so delivery stays consistent cylinder to cylinder even down at the short pulse widths that make most large injectors miserable to tune. Every set ships flow matched, and Injector Dynamics publishes full characterization data, including slope, offset (dead time) versus voltage and pressure, and short pulse width behavior, so your tuner can load real numbers instead of chasing fuel trims across the map. Accurate dead times are what make large injectors behave at idle and cruise, and they are the reason these tune quickly and stay tuned. This configuration uses machined top adapters (already fitted) to suit the rail height listed above. The WRX 16B bottom adapters convert these top feed injectors to drop into the factory Subaru side feed location. If your harness does not have USCAR plugs, plug and play connector adapters are available separately, no cutting or soldering required.
