Prior to the arrival of Precision-Flow™ Fuel Injectors for GM Gen IV engines, performance engine builders were required to retro-fit high-flow Gen III (LS1/LS6) injectors which required a wiring harness adapter to fire the injectors. Most importantly, due to the fact that LS2 and LS7 engines feature shorter fuel injectors than other LS engines, when performance injectors were required engine builders would have to modify the fuel rail placement to fit the Gen III (LS1/LS6) style injectors. The new FAST™ Precision-Flow™ Injectors for GM Gen IV engines are simple drop-in components offered in fuel rates up to 57 lb/hr* (LS2–type) & 65 lb/hr* (LS7/L76/L92-type), the highest rate currently available for GM Gen IV engines.
