Injector Dynamics ID1750-XDS Injectors in the 48 mm Black Bottom Adapter Configuration for the Mitsubishi Evo X
The B in 14B is the part that matters. Injector Dynamics uses it to mark the bottom adapter version of the 48 mm injector, and the importer data behind this listing identifies that adapter as the black one. Against this exact number the manufacturer lists a single application: the Mitsubishi Evo X.
That single row is worth stating plainly, because the research file that fed this rebuild also attached the Mazda Miata 06-14, the Saturn Ion Redline and the Saturn Sky to it. Those three belong to the 60 mm black bottom adapter number, not this one. Same adapter idea, different body length, different part, and the two are not interchangeable in a fuel rail.
Key Features
- Bottom adapter configuration marked 14B in the manufacturer part number, not the plain 14 mm lower O-ring version
- Listed by Injector Dynamics for the Mitsubishi Evo X and no other application under this exact number
- Matched set of four, consistent with the manufacturer's published per-set pricing for this number
- Distinct from the 60 mm black bottom adapter number that serves the Miata 06-14, Saturn and Cobalt SS applications
- Rated at 1728 cc/min at 3.0 bar (43.5 psi) on E10 emissions certification fuel, with a published maximum differential fuel pressure of 7.0 bar
- Compatible with methanol, ethanol, MTBE, nitromethane and all known hydrocarbon fuels, with a USCAR electrical connector
- Published dynamic flow and offset data from 8 to 16 volts across the working pressure range, for direct entry into an engine management system
Fitment
| Years | Make | Model | Notes |
|---|---|---|---|
| Not published | Mitsubishi | Lancer Evolution X | Published as Evo X, the only application row for this exact number |
Injector Dynamics publishes no model years for the Evo X row, so no fitment tag has been created. A tag guessing at production years would be a fabrication, and the master rule here is that only a manufacturer-confirmed bounded vehicle earns one. The Saturn Ion Redline, Saturn Sky and Mazda Miata 06-14 applications that appear near this row in some data sources belong to the 60 mm black bottom adapter part number and have been excluded.

What's Included
- Four Injector Dynamics ID1750-XDS fuel injectors in the 1750.48.14.14B.4 configuration, supplied as one dynamically matched set.
- The manufacturer does not document carton contents for this configuration. Nothing beyond the injectors should be planned into the build without checking the order confirmation.
- The data a tuner needs is published online by Injector Dynamics; nothing about the calibration arrives in the carton.
About Injector Dynamics
Injector Dynamics treats fitment as a configuration problem. The flow rating of the ID1750-XDS never changes between part numbers; what changes is the body length and the top and lower interfaces, and the application table is the only reliable way to pick between them.

FAQ
What does the manufacturer publish for flow?A nominal 1728 cc/min at 3.0 bar (43.5 psi), plus a full slope table across the working pressure range.
What happens above the rated pressure?The manufacturer does not characterise behaviour beyond 7.0 bar differential, so the published ceiling is the working limit.
What limits injector life on corrosive fuels?Injector Dynamics points at filtration and fuel-system maintenance rather than the fuel itself, given the published compatibility list.
What connector should the loom be built to?USCAR, per the manufacturer specification table for this injector.
What happens if the set is split between two engines?The dynamic matching is lost, which is exactly what the manufacturer's matched-set process is intended to prevent.
Are consumables covered?The published term covers manufacturer defects for one year; seals and filtration items are maintenance rather than defects.
What information does the service need?The serial numbers from the base of each connector, which is why they should be recorded before installation.
Does the offset change with voltage?Substantially. The published table runs from 2635 microseconds at 8 volts down to 689 microseconds at 16 volts at 43.5 psid.
Is emissions equipment affected?The manufacturer makes no emissions claims for this injector in either direction, so no compliance statement should be inferred.
What does the B in the part number mean?It marks the bottom adapter version of the 48 mm injector. The importer data for this listing identifies that adapter as the black one, and the store stocks the matching lower adapter O-ring separately.
Which vehicles does this exact number fit?Injector Dynamics lists one application against it: the Mitsubishi Evo X.
Does this fit the Mazda Miata 06-14 or a Saturn Sky?No. Those applications belong to the 60 mm black bottom adapter part number. The body length is different and the parts are not interchangeable.
Why is there no fitment tag on this listing?Injector Dynamics publishes no model years for the Evo X row. Without a manufacturer-confirmed year range there is nothing verified to tag, so the application is documented in the fitment table instead.
Is the Evo IX the same part?No. The Evo III to IX cars are listed against a different configuration with an 11 mm top and a Denso-style lower.
What service seals does this configuration take?A 14 mm top O-ring and the lower adapter O-ring for the black bottom arrangement. Both are catalogued separately by Injector Dynamics.
Installation Instructions
This configuration ships without a published installation procedure. The steps below carry the manufacturer's documented warnings and connector method, and defer all torque and disassembly questions to the factory service information.
- Confirm that part number 1750.48.14.14B.4 is the configuration Injector Dynamics lists for the Mitsubishi Lancer Evolution X before anything is removed from the engine.
- List the four to seven digit serial numbers off the connector bases and file them with the tune, in case the set is ever returned for inspection.
- Depressurise, isolate and only then remove the rail, following the engine manufacturer's published procedure throughout.
- Leave the O-ring retainer fitted. The manufacturer describes removal as irreversible and potentially destructive on the wrong engine.
- Check that the injector seats fully in the rail and in the port with the 48 mm and its listed interfaces before committing to the install.
- Connector build-up is a 5 mm strip, wire seated through the seal and into the terminal, bare conductor set in the crimp section, then a single crimp.
- No pin is designated positive at the injector; Injector Dynamics states the connectors are not polarity specific.
- Every torque figure for this installation comes from the factory service information, not from the injector documentation.
- Download and apply the current ID1750-XDS flow and offset tables to the calibration before the first key-on.
- Build fuel pressure with the engine off and inspect thoroughly; a weeping injector seal on a hot engine bay is not a defect worth discovering by fire.
