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.
This manifold fits cathedral port style heads only. This manifold is recommended for use with an LS3 style MAP sensor. Manifold and fuel rails are designed for use with Bosch EV1 or Magneti Marelli Pico fuel injectors. Fuel rails are machined for -8 AN O-ring female fittings. The LS1 and LS3 Mid-Rise intake manifolds are custom installations and will not accept all OE components.
