Description

Holley EFI LS Mid-Rise intake manifolds are designed for your high performance race engine. They're an excellent choice for street and performance street/strip applications. They're intended for big cube and high-rev applications without height limitations. The modular design of these manifolds offers a runner length and as-cast tapered cross-section design that works for a wide range of engine configurations. 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 Mid-Rise intake manifold bases from Holley.
