Features

  • Vehicle specific kits available for select vehicles.
  • 14002-AF003 for EJ20:
    • The nozzle has 6 holes and 1 jet.
    • Improved injector performance has reduced the invalid injection time compared to the old 800cc (purple) type. (Power supply voltage 14V, fuel pressure 300kPa Old 800cc: 1450μsec ⇒ New 750cc: 1030μsec)
    • A conversion harness is included so that it can be connected to the original harness without any modifications.
    • To improve sealing performance, two O-rings and a backup ring are used at the fuel delivery line connection of the injector.
    • HKS conduct injection tests on all of them, and then put together a kit of four units with similar performance.
