Introducing the HKS 2015-2021 Subaru WRX STI Fuel Upgrade Kit 650 EJ20. HKS Injectors are specifically designed for high-performance applications and are capable of supplying fuel safely and reliably. These injectors can supplement or replace factory-standard injectors, allowing an engine to reach higher horsepower. With sizes ranging from 450cc to 1000cc and two mounting styles (top-feed and side-feed), HKS Injectors can meet many engine tuning needs.


  • Designed with the latest generation BOSCH Top Feed type fuel injector. All injectors have been passed the spray test and similar performance injectors are picked up and packaged in one kit for each car.
  • Improved injector performance results in a shorter injector dead time.
  • (1350?sec => 900?sec at Voltage 14V and Fuel Pressure 300kPa)
  • O-rings(2-pieces) and spacer(back-up ring) have been added to the fuel line connector for improving sealing.
  • Stock harness connector converter is included.
  • Includes same fuel pump in our previous fuel upgrade kit. Replacing connector and small modification of fuel case are necessary when installing to GRB/GVB. (same as previous kit)
