Injector Dynamics 1750-XDS Top Feed Fuel Injectors
2013–2021 Subaru BRZ
1750.18.04.36.11.4
Overview:
The Injector Dynamics 1750-XDS fuel injectors are high-performance top feed injectors designed specifically for the Subaru BRZ model years 2013 through 2021. As the successor to the popular ID1700, these injectors deliver improved flow rates and enhanced fuel delivery precision, making them ideal for enthusiasts running boosted engines or high horsepower setups. Whether you are running E85 or gasoline, the ID1750-XDS offers reliable, consistent fueling with excellent compatibility across all known automotive fuels.
These injectors are engineered for drivers seeking dependable performance upgrades that support aggressive tuning and increased power output without sacrificing drivability or fuel system stability.
Key Features:
The ID1750-XDS injectors incorporate advanced technology and materials to ensure superior performance and durability. Key features include:
- Nominal flow rate of 1728cc/min at 3.0 bar (43.5 psi) using E10 fuel at 49°C (120°F), supporting high horsepower applications.
- Improved dynamic flow rate compared to the ID1700, with no increase in minimum fuel mass for better fuel atomization.
- Enhanced cylinder-to-cylinder balance at low pulse widths, promoting smoother engine operation and consistent combustion.
- Advanced pressure sensitivity improvements for stable performance under varying fuel pressures up to a maximum differential of 7.0 bar (101.5 psi).
- Corrosion-resistant internals compatible with all known automotive fuels including methanol, ethanol, MTBE, nitromethane, and hydrocarbons.
- Unique magnetic circuit design developed in partnership with Bosch Motorsport to eliminate voltage and pressure sensitivity issues common in other high-impedance, high-flow injectors.
- USCAR electrical connector compatibility for seamless integration with factory wiring harnesses.
- Designed primarily for delivering E85 in boosted engines or gasoline in extreme high horsepower builds.
Construction & Design:
The ID1750-XDS injectors feature corrosion-resistant materials in all dimensionally critical components, ensuring long-term durability and consistent performance even when exposed to aggressive fuels. The injector’s magnetic circuit was developed through extensive research and testing to provide immunity against voltage fluctuations and pressure sensitivity, common challenges in high-flow injector designs. This results in precise fuel delivery and reliable operation under the demanding conditions of modern high-performance fuel systems.
Installation & Fitment:
These injectors are designed as direct replacements for the factory injectors on Subaru BRZ models from 2013 to 2021. Installation requires re-pinning your factory harness using the included clips and pins, or you can opt for optional plug-and-play adapters for a simpler installation process. The injectors fit the OEM fuel rail and mounting points without modification.
No cutting, drilling, or special tuning is required to install the ID1750-XDS injectors; however, proper ECU tuning is recommended to optimize fueling and performance when upgrading to these high-flow injectors.
What's Included:
- Set of Injector Dynamics 1750-XDS top feed fuel injectors
- Clips and pins compatible with Injector Dynamics injectors for harness re-pinning
Ideal For:
The ID1750-XDS injectors are ideal for Subaru BRZ owners who:
- Are running boosted or high-horsepower naturally aspirated engines
- Use E85 or other high-ethanol-content fuels
- Require reliable, consistent fuel delivery under high pressure and demanding conditions
