HKS Injectors are precision units engineered to deliver the fuel needed on high-performance applications. When an engine's horsepower is limited by the factory fuel injectors, larger HKS Injectors can be used in addition to or to replace the factory injectors. This allows higher horsepower to be achieved. HKS Injectors range from 450cc to 1000cc, and are available in top-feed or side-feed.

Features:

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)
