PRODUCT DETAILS
Injector Dynamics 1050x fuel injector set for 2012 to 2015 Honda Civic Si with K24Z7 is what you buy when the stock injectors stop keeping up, or when you get tired of chasing a clean idle after mods. These are high impedance, matched port injectors that drop into the K24Z7 intake manifold fuel rail setup, so your ECU still controls fuel the normal way, pulse width plus fuel pressure plus proper injector data.
On a bolt on car, factory injectors usually behave. Start leaning on the setup, more airflow, more boost, or Civic Si E85 fuel injectors become mandatory, and the OEM parts turn into the bottleneck fast. The Injector Dynamics 1050x Civic Si set fixes that with more headroom and real published characterization data from Injector Dynamics, which means your tuner can scale them correctly instead of guessing. It also stays high impedance, so you do not need a resistor box, and you keep typical modern ECU control strategies happy.
For fitment, the ID1050x uses a compact 48 mm body intended to package in the Civic Si rail and manifold without spacers. Injector Dynamics rates these at 1065 cc per minute at 3.0 bar on gasoline at 52 degrees C, with a published maximum differential fuel pressure of 10.0 bar. The injector itself uses a USCAR connector. Injector Dynamics also calls out corrosion resistant internals and states compatibility with all known fuels, plus you get a replaceable inlet filter, which is nice when your fuel system is not always as clean as you swear it is.
In the real world, that extra flow plus known data is why people run ID1050x injectors for Civic Si builds, including Civic Si race fuel injectors setups and ID1050x turbo injectors Civic combos. You get the headroom to keep duty cycle in a safer range, and you get better control at short pulse widths than a lot of big injectors that idle like a forklift. We still use these exact injectors on our own cars when we need high flow Civic Si injectors that tune predictably.

Installation and calibration considerations Treat this like any real fueling change. Your tuner must update injector scaling and offset using the correct Injector Dynamics data for the ID1050x, not some random “close enough” injector file. Respect the 10.0 bar differential pressure limit, and make sure your pump, regulator, lines, and filter actually support the pressure and flow you target. Choose the kit that matches your wiring needs: SKU: IJD-1050-K24Z-PNP includes Pigtails: Yes, and SKU: IJD-105007214814 ships with Pigtails: No. If you are specifically hunting Injector Dynamics injectors Civic Si for a K24Z7, this is the straightforward Civic Si K24Z7 fuel injectors option that tuners recognize.
