Injector Dynamics ID1750-XDS Injectors for Audi and Volkswagen EA888 Gen 3 Engines
Injector Dynamics lists part number 1750.34.14.14.4 under both Audi and Volkswagen for the EA888 Gen 3 engine, and supplies it as a set of four. Because the application is defined by the engine generation rather than by a car, the engine has to be identified before ordering.
The set uses the 34 mm short-body configuration with 14 mm top and lower interfaces. Injector Dynamics builds the ID1750-XDS specifically for motorsport service and lists it as compatible with methanol, ethanol, MTBE, nitromethane and all known hydrocarbon fuels.
Key Features
- Supplied as a dynamically matched set of four injectors in the 1750.34.14.14.4 configuration
- Every dimensionally critical internal part made from corrosion-resistant material, per the X-Series design brief
- High-flow motorsport injector rated at 1728 cc/min at 3.0 bar on E10 certification fuel
- Compatibility with methanol, ethanol, MTBE, nitromethane and all known hydrocarbon fuels
- USCAR electrical connector
- Published dynamic flow and offset data from 8 to 16 volts across the full pressure range
- Listed by Injector Dynamics for Audi and Volkswagen EA888 Gen 3
Fitment
Both manufacturer entries name an engine generation, not a vehicle, so this listing carries no vehicle-year fitment tags. Confirm that the engine is an EA888 Gen 3 and that its port injection rail accepts the 34 mm configuration.

What's Included
- 4 Injector Dynamics ID1750-XDS fuel injectors in the 1750.34.14.14.4 configuration, supplied as one dynamically matched set.
- Injector Dynamics does not publish a packaged-contents list for this part number, so no adapters, O-rings, seals, pigtails, connectors or mounting hardware should be assumed beyond the injectors themselves.
- Dynamic flow and offset characterization data is published by Injector Dynamics online rather than supplied as a printed insert.
About Injector Dynamics
Injector Dynamics positions the ID1750-XDS as the high-flow step in its motorsport range, rated on E10 certification fuel and listed as compatible with methanol, ethanol, MTBE, nitromethane and all known hydrocarbon fuels. Every application in its catalogue points at an exact configuration and set quantity rather than a generic flow figure.

FAQ
What is the nominal flow of the ID1750-XDS?1728 cc/min at 3.0 bar (43.5 psi), measured with E10 emissions certification fuel at 49 C (120 F), as published by Injector Dynamics.
Is there a limit on base fuel pressure?Yes. The manufacturer specifies a maximum differential fuel pressure of 7.0 bar (101.5 psi).
Can these be run on ethanol?The manufacturer fuel compatibility statement reads: Compatible with methanol, ethanol, MTBE, nitromethane and all known hydrocarbon fuels.
What electrical connector is fitted?The manufacturer specification is a USCAR connector.
Is this a matched set or loose injectors?It is a matched set. Injector Dynamics dynamically matches injectors together rather than shipping unmatched singles.
What warranty applies?Injector Dynamics states a warranty period of one year from the date of original purchase covering manufacturer defects.
Can the retainer be put back on after removal?No. Injector Dynamics states that once the molded O-ring retainer is removed it cannot be refitted.
Does the manufacturer service its own injectors?It does. The cleaning and inspection service requires every injector in the set and identifies them by the serial number at the base of the connector.
What data does the tuner need?The published dynamic flow and offset values across the voltage and pressure range for this injector model.
Which cars use the EA888 Gen 3?Injector Dynamics does not publish a vehicle list against this entry, so the engine itself has to be identified on the car rather than inferred from a model name.
Do these replace the direct injectors on an EA888 Gen 3?No. These are port-style injectors with a USCAR connector supplied in the 34 mm configuration Injector Dynamics lists for the application, so the rail they are going into must accept that configuration.
Is the earlier EA888 covered?The manufacturer entry names Gen 3 specifically, and separate part numbers are listed for the older 1.8T and VR6 engines, so earlier generations are outside the scope of this set.
Installation Instructions
The manufacturer publishes cautions, connector guidance and characterization data, but no step-by-step installation procedure for this part number. Treat the factory service information for the engine as the authority on rail removal and fastener torque.
- Confirm that part number 1750.34.14.14.4 is the configuration Injector Dynamics lists for Audi and Volkswagen EA888 Gen 3 engines before removing anything from the engine.
- Note the serial numbers stamped at the base of each connector so the set can be identified later; Injector Dynamics requires them for service requests.
- Relieve fuel pressure and isolate the supply, then take the rail off using the factory service information, since no manufacturer removal procedure exists for this configuration.
- Keep the molded O-ring retainer intact. Removal is a manufacturer-directed modification only, and is permanent once done.
- Check that the injector seats fully in both the rail and the port with the 34 mm body and its listed interfaces before committing to the install.
- If the harness needs Injector Dynamics connectors assembled, strip roughly 5 mm of insulation, feed the wire through the seal and into the terminal, align the bare wire with the crimp section of the terminal and crimp it.
- Connect the two pins in whichever order suits the loom. Injector Dynamics states injector connector polarity is not specific.
- Torque the rail and any disturbed fasteners to the values in the factory service information for the engine. Injector Dynamics does not publish torque figures for this part number, so no generic value should be substituted.
- Enter the manufacturer's latest dynamic flow and offset tables for the ID1750-XDS into the ECU before the first start.
- Bring the system up to pressure with the engine off, look hard for leaks at every seal, and confirm the filtration standard the warranty terms depend on.
