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. As boost pressure is increased on forced induction vehicles, the amount of boost that can ultimately be used is limited by the constraints of the engine and injector capacity. When OEM injectors reach their maximum capacity, they can no longer flow any additional fuel for higher boost levels; Therefore larger primary injectors can be installed in the factory location and be controlled by an injector upgrade specific program of the VPC, PFC F-CON, or the F-CON S system. HKS injectors range in size from 188cc to 1000cc and are offered in both hose-end types and OE top feed fuel rail types. Hose-end injectors are typically used with the HKS AIC installation kits for an intake-stream installation. Rail type injectors are used on the factory fuel rails or on vehicle specific, HKS fuel rail upgrade kits or AIC Pipe kits. HKS injector harnesses and other miscellaneous injector hardware and fittings are also available for custom applications.
