Holley EFI LT1 Gen V Hi-Ram intake manifolds provide ultimate performance with GM direct-injected Gen V 6.2L LT1 engines. 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 and cross-sectional area to perform in a wide variety of engine configurations.
They are available with injector bosses on the intake runners that provide increased performance potential by using additional injectors along with the factory direct injection. When you look for the pinnacle of performance, price, and quality; look to Holley EFI.
