The Holley EFI Hi-Ram intake provides the ultimate performance for the GM direct injected Gen V 6.2L LT1 engine. The modular design allows easy disassembly for custom porting, multiple tops, or custom induction systems. Each runner has a large radius where it meets the plenum, and optimized taper & cross-sectional area to perform in a wide variety of engine configurations. The optional injector bosses on the intake runners allow increased performance potential by using additional injectors.
