The Modular Mid-Rise intake utilizes the popular Holley LS1/LS2/LS6 cathedral port Mid-Rise 2 x 4 intake manifold along with a plenum base adapter and a Holley 92MM EFI plenum top which converts it into a Mid-Rise EFI intake manifold.
For use with LS Dual Plane Mid-Rise intake manifold base to adapt to modular tops.
