Injector Dynamics ID1750-XDS Injectors for the Audi RS3 and TT RS
Injector Dynamics lists part number 1750.34.14.14.5 under Audi for the RS3 and TT RS, and supplies it as a set of five to suit the five-cylinder engine those cars share. The manufacturer does not publish model years against the entry, so the car and its fuel rail should be identified before ordering.
This is the 34 mm short-body configuration with 14 mm top and lower interfaces. The ID1750-XDS behind it is rated at 1728 cc/min at 3.0 bar on E10 certification fuel, with a maximum differential fuel pressure of 7.0 bar.
Key Features
- Supplied as a dynamically matched set of five injectors in the 1750.34.14.14.5 configuration
- 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
- 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
- Listed by Injector Dynamics for Audi RS3 and TT RS
Fitment
One manufacturer entry covers both cars and it carries no published years, so this listing does not claim vehicle-year fitment tags. The five-injector set quantity matches the five-cylinder engine used in both models.

What's Included
- 5 Injector Dynamics ID1750-XDS fuel injectors in the 1750.34.14.14.5 configuration, supplied as one dynamically matched set.
- Because Injector Dynamics documents no packaged contents for this part number, nothing beyond the injectors should be counted on, including seals, spacers and wiring components.
- Injector Dynamics distributes its dynamic flow and offset data digitally, and states that the data is under continual improvement.
About Injector Dynamics
The ID1750-XDS is the large-capacity member of the Injector Dynamics X-Series, published with a full dynamic flow table from eight to sixteen volts across the pressure range. Injector Dynamics catalogues it application by application, and matches the injectors as a group before they leave the building.

FAQ
How much fuel does this injector flow?Injector Dynamics rates the ID1750-XDS at 1728 cc/min at 3.0 bar (43.5 psi), measured with E10 emissions certification fuel at 49 C (120 F).
What differential pressure is the injector rated for?7.0 bar (101.5 psi), per the manufacturer specification table.
Will corrosive fuels shorten injector life?Injector Dynamics publishes compatibility as follows: Compatible with methanol, ethanol, MTBE, nitromethane and all known hydrocarbon fuels. The warranty terms still require correct fuel type and filtration.
Is the connector polarity sensitive?The connector is a USCAR type, and Injector Dynamics states its injector connectors are not polarity specific, so power or ground can go to either pin.
Why buy the set rather than individual injectors?Injector Dynamics matches injectors dynamically as a group, and its service department asks for the complete set when work is needed.
Is there a warranty on these injectors?Yes, one year from the date of original purchase against manufacturer defects.
What is the plastic retainer on the injector body?It is the molded O-ring retainer fitted to all Injector Dynamics injectors. It should only be removed on the manufacturer's instruction, and it cannot be refitted.
How is a suspect injector diagnosed?Injector Dynamics asks for the four to seven digit serial number found at the base of the connector, then processes the full set through its cleaning and inspection service.
Do these need a retune?Yes. Injector Dynamics publishes dynamic flow and offset characterization data so the engine management system can be configured for the injector before the engine is run.
Does the entry cover every RS3 and TT RS generation?Injector Dynamics publishes the application as Audi RS3/TTRS with no year split, so the injector pocket and rail on the specific car should be verified rather than assuming full generational coverage.
Why five injectors rather than four or six?The RS3 and TT RS use a five-cylinder engine, and the manufacturer publishes this configuration in a quantity of five so a single matched set covers the engine.
Are these a direct swap for the factory port injectors?The manufacturer lists the configuration but does not publish a direct-replacement claim, so the rail interface, injector length and electrical connector should all be checked against the car.
Installation Instructions
Injector Dynamics publishes no installation procedure or torque values against this part number, so the steps below cover only its documented cautions and connector guidance and point to factory service information for the rest.
- Confirm that part number 1750.34.14.14.5 is the configuration Injector Dynamics lists for the Audi RS3 and TT RS before removing anything from the engine.
- Log the serial number on each injector body at the base of the connector. It is the identifier the manufacturer uses for any warranty or service claim.
- Depressurise and isolate the fuel system, then remove the fuel rail following the factory service information for the engine, because Injector Dynamics does not publish a removal procedure for this configuration.
- Do not trim the molded O-ring retainer. The manufacturer states the modification should only be performed when it instructs you to, and that it cannot be reversed.
- 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.
- Building the plugs is a five millimetre strip, wire through the seal and into the terminal, bare conductor aligned with the crimp section, then crimp, following the manufacturer's connector guidance.
- There is no correct pin order for power and ground at the injector; the manufacturer states the connectors are not polarity specific.
- Use the factory service information for every fastener torque. The manufacturer publishes no torque specification for this configuration, and a generic figure should not be invented in its place.
- Pull the newest published characterization data for the ID1750-XDS and enter it into the engine management system ahead of the first start.
- Pressurise the fuel system with the engine stopped, inspect every joint for leaks, and confirm proper fuel filtration is in place, which the manufacturer requires for warranty coverage.

Fuel Injector Sets - 5Cyl
A matched set of fuel injectors ensures balanced fuel delivery across every cylinder in 5-cylinder engine applications, preventing the cylinder-to-cylinder variation that causes rough idle, uneven power distribution, and difficulty achieving correct air-fuel ratios across the entire rev range. Factory injectors lose flow capacity and spray pattern quality over time due to deposits, coking near the injector tip, and solenoid wear, making a complete set replacement more reliable than swapping a single injector after a misfire diagnosis. Flow-matched injector sets are especially important on high-performance builds where uneven fueling translates directly into inconsistent combustion and wasted tuning effort. Whether replacing worn OEM injectors or stepping up to a higher flow rate for a forced induction build, buying a matched set is the correct approach for consistent results. Popular Upgrades Top-selling 5-Cylinder injector sets include Bosch EV14 matched sets for turbocharged appli...
