GM Gen V Stage 1 Fuel Injector Set

The Lingenfelter NOSTRUM GM GEN V Stage 1 Fuel Injectors are a direct replacement set designed to increase fuel flow for enhanced performance. These injectors flow 25% more than stock LT4 injectors and 45% more than stock LT1/L86 injectors. They are compatible with gasoline and E85 fuel, supporting up to 1200 wheel horsepower on gasoline and 900 wheel horsepower on E85.

Each injector is individually tested and dynamically batched into sets to ensure minimal variance. They feature an OEM equivalent spray pattern, which is crucial for proper idle quality, drivability, and engine longevity. These injectors are fully controllable with the factory engine management system and require tuning using software like HP Tuners or EFILive.
