    Holley 300-128 Details

    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.

    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.
