All GM LS Gen III or IV engines equipped with LS3/L92 style rectangular ports. Mid-Rise EFI Intake Manifold Kit. 1500-6500RPM Power Band.

The Modular Mid-Rise intake utilizes the popular Holley LS3/L92 rectangle port Mid-Rise intake manifold along with a purpose built plenum base adapter and a Holley 105MM 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 turbocharged, or naturally aspirated applications. This manifold is modular, and the plenum adapter (PN 300-231) will accept all of the popular Holley LS Hi-Ram plenum tops as a foundation for custom induction systems. *** The front and rear height measurements listed in the Specs section are referencing the overall height with the top plate installed. Please see the diagrams in the product images for other dimensions.
