ID1750-XDS Injectors in the 14mm purple top / 14mm lower O-ring Configuration (Set of six)
Injector Dynamics part number 1750.60.14.14.6 is the ID1750-XDS configuration built around a 14mm purple top and 14mm lower O-ring, supplied here as a matched set of six. 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.
The manufacturer lists this exact part number as a Universal configuration, while also showing it under several six-injector vehicle applications on the same page. Because the manufacturer's own listing for this exact MPN is the Universal row, this product is catalogued as universal rather than tied to one vehicle.
Key Features
- 14mm purple top / 14mm lower O-ring interface, dynamically matched as a set of six
- 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
- Six Injector Dynamics ID1750-XDS fuel injectors in the 14mm purple top / 14mm lower O-ring 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 1750.60.14.14.6 describe?A ID1750-XDS injector in the 14mm purple top top / 14mm lower O-ring lower interface, supplied as a matched set of 6.
Are the injectors in this set dynamically matched?Yes. Injector Dynamics dynamically matches the set before it leaves the factory and identifies each unit by the serial number at the base of its connector.
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?The manufacturer lists this exact part number as a Universal configuration, while also showing it under several six-injector vehicle applications on the same page. Because the manufacturer's own listing for this exact MPN is the Universal row, this product is catalogued as universal rather than tied to one vehicle.
Does the set include a retune?No. Injector Dynamics treats characterization as ongoing published data rather than a one-time printed spec, so check for the latest table before finalizing the tune.
Can the molded O-ring retainer be removed from these injectors?Only where Injector Dynamics' own documentation calls for it. The manufacturer is clear that incorrect removal risks catastrophic engine damage and cannot be reversed.
What warranty applies to this injector set?The published term is one year from original purchase against manufacturer defects; Injector Dynamics will not cover damage from the wrong fuel or poor filtration practice.
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 1750.60.14.14.6 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.
- No, unless the manufacturer's own guidance for that application calls for it; this is a one-way, application-specific modification with real engine-damage risk if done incorrectly. 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 14mm purple top and 14mm lower O-ring 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).
- Start the engine, check for fuel leaks at the rail and injector seats, and confirm stable idle before road use.
