ID1750-XDS Injectors in the 11mm blue top / Denso lower cushion Configuration (Set of four)
Injector Dynamics part number 1750.60.11.D.4 is the ID1750-XDS configuration built around a 11mm blue top and Denso lower cushion, supplied here as a matched set of four. Injector Dynamics numbers its X-Series injectors so that body length, top interface and lower interface are fixed by the part number rather than left to the installer, and this exact number ties to the application rows described below.
Manufacturer application rows list this exact configuration for the Scion xB above; separate universal ID1750 configurations exist under different part numbers.
Key Features
- 11mm blue top / Denso lower cushion interface, dynamically matched as a set of four
- Rated at 1728 cc/min at 3.0 bar (43.5 psi), measured on E10 emissions certification fuel at 49 C (120 F), with a published maximum differential fuel pressure of 7.0 bar (101.5 psi)
- Compatible with methanol, ethanol, MTBE, nitromethane and all known hydrocarbon fuels, with a USCAR electrical connector

What's Included
- Four Injector Dynamics ID1750-XDS fuel injectors in the 11mm blue top / Denso lower cushion configuration, supplied as one dynamically matched set.
- Injector Dynamics publishes no packing list beyond the injectors for this part number; treat adapters, spare O-rings, pigtails and mounting hardware not already part of the injector body as separate purchases.
- Dynamic flow and offset characterization data is published separately online by Injector Dynamics and is not a physical item in the package; pull the current version before tuning.
About Injector Dynamics
Injector Dynamics catalogues its X-Series injectors by exact application rather than by a single generic part number, tying body length, top interface and lower interface together in the part number itself. The ID1750-XDS sits in that system as a ID1750-XDS-class injector, and every set ships dynamically matched so the group's flow behaviour tracks together rather than being assembled from unmatched singles.
FAQ
What configuration does Injector Dynamics part number 1750.60.11.D.4 describe?A ID1750-XDS injector in the 11mm blue top top / Denso lower cushion lower interface, supplied as a matched set of 4.
Are the injectors in this set dynamically matched?Yes. The manufacturer matches injectors dynamically before shipment and asks that the full set be returned together for any later cleaning or inspection.
What fuels can this injector run?Compatible with methanol, ethanol, MTBE, nitromethane and all known hydrocarbon fuels, per the manufacturer specification for the ID1750-XDS family.
What is the nominal flow rating?1728 cc/min at 3.0 bar (43.5 psi), measured on E10 emissions certification fuel at 49 C (120 F), as published by Injector Dynamics for the ID1750-XDS.
What is the maximum differential fuel pressure?7.0 bar (101.5 psi), per the manufacturer specification table.
What electrical connector does this injector use?A USCAR connector, per the manufacturer specification table.
Is vehicle fitment for this exact configuration confirmed by Injector Dynamics?Manufacturer application rows list this exact configuration for the Scion xB above; separate universal ID1750 configurations exist under different part numbers.
Does the set include a retune?No, the set ships without a printed data sheet. The manufacturer's offset and slope values are published online and should be downloaded fresh for the tune.
Can the molded O-ring retainer be removed from these injectors?Only under Injector Dynamics' direct instruction for that exact application; the company warns of catastrophic engine damage from doing this incorrectly, and it cannot be reversed.
What warranty applies to this injector set?A one-year warranty from original purchase against manufacturer defects; Injector Dynamics excludes issues caused by unsuitable fuel or insufficient filtration.
Installation Instructions
Injector Dynamics publishes cautions, connector guidance and characterization data for this injector, but no vehicle-specific procedure and no torque figures. The sequence below stays inside what the manufacturer states and hands everything else to the factory service information.
- Confirm that part number 1750.60.11.D.4 is the exact configuration Injector Dynamics lists for this application before removing anything from the engine.
- Record the four-to-seven digit serial number at the base of each injector connector before installation; Injector Dynamics identifies sets by these numbers for any later service.
- Depressurize and isolate the fuel system, then remove the rail per the factory service information for the engine.
- Only where Injector Dynamics' own documentation calls for it. The manufacturer is clear that incorrect removal risks catastrophic engine damage and cannot be reversed. Do this check before any injector goes into the rail.
- Check that each injector seats fully in the rail and in the port with the 11mm blue top and Denso lower cushion described above before committing to the install.
- Connect the USCAR connectors per the harness wiring, using a proper crimp rather than a pierce or tap connection.
- Injector Dynamics states its connectors are not polarity-specific, but verify the harness wiring matches the engine management system's expected polarity before powering up.
- Torque the fuel rail fasteners to the vehicle manufacturer's specification; Injector Dynamics does not publish injector-specific torque values.
- Load the current published dynamic flow and offset data for the ID1750-XDS into the engine management system before starting the engine (no physical calibration sheet is included).
- Start the engine, check for fuel leaks at the rail and injector seats, and confirm stable idle before road use.
