Injector Dynamics ID1050-XDS Fuel Injectors | Set of 4 | 1990-2005 Mazda MX-5 Miata (1050.11.02.60.11.4-PU)

Maxed-out injectors turn every dyno pull into a gamble.

Once boost and ethanol enter the picture, factory injectors become the first hard ceiling in the whole combination. The ID1050-XDS answers that with 1065cc/min of flow at 3.0 bar, compatibility with all known fuels including E85, delivered as a matched set of 4 for your 1990-2005 Mazda MX-5 Miata. Each set is flow matched using Dual Slope Matching and backed by full characterization data, so your ECU gets real numbers, not estimates. Fueling you can build a tune on.

What You'll Feel

• Crisp part-throttle response instead of the surge and stumble big injectors are known for
• Steady AFRs when boost climbs, no lean spikes at the top of the pull
• Cylinder-to-cylinder consistency you can see in your lambda and EGT logs
• Stock-like idle and clean cold starts, even at this injector size
• Fuel trims that stay put season to season instead of drifting with the weather

Features

• Nominal flow rate: 1065cc/min at 3.0 bar (43.5 psi), measured with gasoline at 52 degrees C (125 degrees F)
• Maximum differential fuel pressure: 10.0 bar (145.0 psi)
• Compatible with all known fuels, including gasoline, E85, and ethanol blends
• Corrosion resistant internals for extended service life on ethanol and other corrosive fuels
• Replaceable inlet filter for longer service life
• USCAR electrical connector, supplied with potted plug and play wiring adapters
• Configuration: 60mm body, 11mm top, application-specific lower fitment
• Supplied as a flow-matched set with Dual Slope Matching for consistent delivery at low pulse widths

The Details

The ID1050-XDS is the current evolution of the ID1050x, built to spec with Bosch Motorsport rather than modified from a production part. Compared to the original ID1000 it gains an improved internal flow path (about 5 percent more output with no loss of low-flow control), a stronger magnetic circuit that stays stable up to 10 bar, and a replaceable inlet filter. 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 an application-specific part number with machined fitment hardware, so it drops in without guessing at adapters. Potted plug and play wiring adapters are included, because a standard connector will not clear the cylinder head on this application.

Fitment Notes
