Description

Holley EFI GM Gen V LT Hi-Ram Lower Manifold w/Port Provisions, Fuel Rails 300-236

LT1 Hi-Ram, Lower Manifold Only w/Port EFI Provisions & Fuel Rails. Order Plenum Top Separately.

The new Holley EFI Hi-Ram intake provides the ultimate performance with the new GM direct-injected Gen V 6.2L LT1 engine. The modular design of this manifold 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 along with the factory direct injection. When you look for the pinnacle of performance, price, and quality, look to Holley EFI.
