PRECISION-FLOW™ FUEL INJECTORS FOR GM GEN IV ENGINES
New FAST™ injectors feature highest flow rate of any injector specifically designed for
2005-2008 LS2/LS7/L76/L92 engines
The FAST™ Precision-Flow™ Fuel Injectors for GM Gen IV engines are the highest flowing
injectors available and are uniquely designed for direct installation into LS2 and LS7/L76/L92-
style engines. Available in two different height configurations and a wide range of flow rates, the
new Precision-Flow™ Fuel Injectors are correctly sized (shorter than the common LS1/LS6
injectors) and feature the correct USCAR connector, enabling hassle-free plug-in operation. In
addition, the high-impedance, high-flow FAST™ injectors meet/exceed all factory durability
standards and quality tolerances.
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.
