Injector Dynamics ID1750-XDS Fuel Injectors | Set of 4 | 2022-2026 Polaris RZR / Audi EA888 Gen 3 / Volkswagen EA888 Gen 3 (1750.34.14.14.4)

Duty cycle pegged at 95 percent is not a tune, it is a warning.

A factory fuel system that was sized for stock power runs out of injector long before a built engine runs out of airflow. The ID1750-XDS answers that with 1728cc/min of flow at 3.0 bar, compatibility with methanol, ethanol, and all known hydrocarbon fuels, delivered as a matched set of 4 for your 2022-2026 Polaris RZR / Audi EA888 Gen 3 / Volkswagen EA888 Gen 3. Each set is flow matched using Dual Slope Matching and backed by full characterization data, so your ECU gets real numbers, not estimates. Sized right, characterized right, tuned right.

What You'll Feel

• Fuel trims that stay put season to season instead of drifting with the weather
• Faster dyno sessions, because accurate injector data means less time chasing fuel trims
• Cylinder-to-cylinder consistency you can see in your lambda and EGT logs
• Headroom to grow the build without touching the fuel system again
• Stock-like idle and clean cold starts, even at this injector size

Features

• Nominal flow rate: 1728cc/min at 3.0 bar (43.5 psi), measured with E10 emissions certification fuel at 49 degrees C (120 degrees F)
• Maximum differential fuel pressure: 7.0 bar (101.5 psi)
• Compatible with methanol, ethanol, MTBE, nitromethane, and all known hydrocarbon fuels
• Corrosion resistant construction for long service life on alcohol fuels
• USCAR electrical connector
• Configuration: 34mm body, 14mm top (no adapter), 14mm lower o-ring
• Supplied as a flow-matched set with Dual Slope Matching for consistent delivery at low pulse widths

The Details

The ID1750-XDS is the successor to the ID1700x. It adds a higher dynamic flow rate with no increase in minimum fuel mass, better cylinder-to-cylinder balance at low pulse widths, and improved pressure sensitivity, while keeping the "compatible with everything but dirt" corrosion resistance the 1700 was known for. It sits between the 1300 and 2600 in the XDS lineup, sized for serious ethanol and methanol builds that have outgrown the 1300 class. Every set ships flow matched, and Injector Dynamics publishes full characterization data, including slope, offset (dead time) versus voltage and pressure, and short pulse width behavior, so your tuner can load real numbers instead of chasing fuel trims across the map. Accurate dead times are what make large injectors behave at idle and cruise, and they are the reason these tune quickly and stay tuned. This is the short 34mm body with no top adapter, a direct fit where the rail was designed for short injectors. If your harness does not have USCAR plugs, the matching ID plug and play adapter is 91.3 (USCAR to Denso), available separately, no cutting or soldering required.
