For use with LS Dual Plane Mid-Rise intake manifold base to adapt to modular tops.

The Modular Mid-Rise intake utilizes the popular Holley LS1/LS2/LS6 cathedral port Mid-Rise 2 x 4 intake manifold along with a purpose built plenum base adapter and a Holley 92MM EFI plenum top which converts it into a Mid-Rise EFI intake manifold. With a max overall height of only 10.44", the Mid-Rise manifold is an excellent choice for street and performance street/strip applications with a powerband from 1,500-6,500 RPM and limited hood clearance. It's perfect for a blow-thru or turbocharged application.

Being part of the Holley modular intake line means that this intake is not only available as a complete kit with intake, adapter, 92MM top and fuel rails, but all parts can also be purchased separately for a custom intake build. The plenum adapter (PN 300-231) will accept all of the popular Holley Hi-Ram plenum tops as a foundation for custom induction systems.
