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 inch, 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 300-267BK) will accept all of the popular Holley Hi-Ram plenum tops as a foundation for custom induction systems.

Features and Benefits:

  • Provides great performance to 6500 rpm for street/strip performance applications while providing the look of a racing EFI intake manifold Unique modular design allows the combination of a traditional dual-plane layout with an EFI manifold plenum to produce great mid-range torque without compromising top end power Great for supercharged or turbocharged engines Power band from 1500-6500 rpm May require an aftermarket hood for some vehicle applications
  • Cast aluminum construction Intended for use on all Gm Ls Gen Iii or Iv engines equipped with LS1/LS2/LS6 style cathedral port cylinder heads (recalibration of the ECU may be required when using this intake manifold design with Oe ECU)
  • Black Ceramic Coating for an aggresive look in your engine compartment

Associated Comments:

  • Holley EFI Ls main harnesses have a map sensor connecter designed for use with an LS1/2 style map sensor. The 558-416 is an adapter harness that can be used to adapt any Ls harness that uses a LS1/2 Map sensor connection to a LS3 Map, which is recommended for this manifold.
