| Description_MKT | Single Plane EFI LS Intake Manifold. All GM LS Gen III or IV engines equipped with LS1/LS2/LS6 style cathedral port cylinder heads. |
| Description_MKT | 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 10.44in., 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. |
