These are designed for the new GM LT series engines. With a 30% increase in flow over stock LT4 injectors, these supply the needed fuel flow for high horsepower applications without having to resort to auxiliary fuel systems. These injectors utilize the same nozzle that was designed by GM, which is the best design for these engines. All modifications are internal utilizing the same coil and original characteristics programmed in the ECU from GM.

Testing done by major companies such as Lingenfelter Engineering and Vengeance Racing have shown excellent results in tuning by just modifying the fuel tables and leaving the offsets alone. The injectors are E85 compatible allowing higher output engines to take advantage of the capability of E85 fuel.

Helpful Tip: It has been known for some time that the LT direct injection engines are limited on fuel. To date the best combo seems to be using FIC’s 30% over injectors, stock LT4 high side fuel pump, inline low side fuel pump, and a 32%+ camshaft lobe. The Lingenfelter high side pump while still a good pump is limited to a smaller fuel pump lobe than the factory LT4 pump, and has been known to not produce as much volume as the above stated combo.
