Holley Tunnel Ram Intake ManifoldsPLENUM TOP HI-RAM 105MM
Holley EFI LS Hi-Ram intake manifold bases are designed for your high performance race engine. Big cube and high-rev applications without height limitations are the intent for these cast aluminum EFI bases. The modular design of these Holley Hi-Ram bases offers a runner length and as-cast tapered cross-section design that works for a wide range of engine configurations. This makes them a great foundation for building or fabricating your custom induction system. The included 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. Build maximum performance with EFI LS Hi-Ram intake manifold bases from Holley.
