Holley EFI LT1 Gen V Hi-Ram intake manifolds provide the 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. When you look for the pinnacle of performance, price, and quality, look to Holley Hi-Ram intake manifolds for your LT1 application. Features include: * Available with injector bosses on the intake runners that provide increased performance potential by using additional injectors and the factory direct injection * Removable top * Large plenum volume * Intakes with injector ports include fuel rails with dual mounting * Fuel rails are anodized, laser-etched, and machined for -8 AN O-ring fittings at each end * Rear of plenum machined for MAP sensor and three vacuum ports * Head flange has clearance for fuel supply to a high-pressure pump * Increased runner wall thickness for custom porting at the plenum to runner entry on each runner * O-ring seals at cylinder heads and plenum top * Easy assembly with top-mounted screws on plenum top (except front two screws) * Several top options: 1 x 95mm, 1 x 105mm, 2 x 4150, 2 x 4500, or blank flange for custom throttle bodies * 3,500 to 8,000-plus rpm power band
