Description

Make Holley SBF Hi-Ram EFI intake manifold bases the foundation for your custom induction system. Their modular design allows them to accept a variety of carbureted and EFI tops. Plus, their runner length and tapered cross-section are designed to perform well for a wide range of engine configurations. Aggressive looks and bold styling make your bad intentions clear—whether you're drag racing, truck pulling, or making waves in your boat—when you start with the Holley Hi-Ram EFI intake manifold bases.

SBF Hi-Ram EFI intake manifold base features and specs:

* Manifold base only designed for 8.2 in. deck height
* Cast aluminum construction
* Available in natural cast aluminum (satin) or black powdercoat finish
* EFI fuel rails are machined for -8 AN O-ring fittings, with passages large enough to accommodate high fuel flows and dampen pressure pulsations in the fuel system
