The Bosch Motorsport EV14 injectors were originally developed for use in the Shelby GT500, but with our innovative top injector hats, we have adapted these for use in our Honda/Acura applications and paired this with dead-on injector data. This allows a true plug-n-play injector set. Simply install on your engine, then use our plug-n-play data to program your ECU with the correct injector data.

These injectors use the common "USCAR" electrical connectors. In order to plug these in to your wire harness, you can either cut and crimp the USCAR clips and pins onto your harness, use the OBD1 plug-n-play adapters, or use the OBD2 plug-n-play adapters.


  • Set of 4 matched 520cc injectors
  • Set of 4 clips with pins and seals (for crimping onto your factory wiring, or choose one of our OBD1 or OBD2 plug-n-play wiring adapters from the drop-down menu).
