ID1050-XDS, for 06-11 Civic Si / K-series. 14mm (grey) adapter top. Set of 4.
The ID1050-XDS is the evolution of the ID1050x.
The ID1050-XDS benefits from Dual Slope Matching, a method of matching the flow rate in both the linear, and nonlinear operating range, providing better cylinder to cylinder consistency at low pulse widths.
Corrosion resistant internals make it compatible with all known fuels, capable of extended service life with corrosive fuels.
Compact body allows fitment in 200+ applications, including current and future engines utilizing short body injectors.
Stronger magnetic circuit offers stable operation up to 10 bar.
Replaceable inlet filter extends service life.

The ID1050-XDS (1050 cc/min at 43.5 psi) is a high-flow solution for K-series engines in the Civic 06-11. This 4- or 8-injector set provides sufficient fueling for high-performance naturally aspirated or turbocharged builds, reliably supporting wheel horsepower well into the 450+ WHP range on E85, giving your Civic a safe fuel margin for aggressive tuning.
Yes. This ID1050-XDS set is configured to the correct 48mm O-ring-to-O-ring length standard for Civic K-series applications. It installs directly into the factory fuel rail and intake manifold bosses without spacers or modifications, providing a true drop-in upgrade.
No adapters are required. The ID1050-XDS injectors feature USCAR-style connectors that are compatible with the factory wiring harness on the Civic 06-11, allowing plug-and-play installation without cutting or splicing.
Injector Dynamics provides validated Dead Time (Latency), Short Pulse Adder tables, and Flow vs. Pressure data specifically for K-series Honda engines. This data is essential for tuning with Hondata, KTuner, or other compatible platforms to achieve stable idle, precise fueling, and consistent air/fuel ratios under all operating conditions.
Due to the precision internal clearances of the ID1050-XDS injectors and the corrosive nature of E85, a high-quality post-pump fuel filter is mandatory. Injector Dynamics recommends a 10-micron or finer filter to protect the stainless steel internals and ensure long-term injector reliability for high-performance Civic builds.
