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 turbocharged, or normally 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.
- Provides great performance to 6500 rpm for street/strip
performance applications while providing the look of a racing EFI
- 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
- 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).
- 92MM EFI Plenum Top
- Black Ceramic Coating provides an aggressive look for your
Recalibration of the ECU may be required when using this intake
manifold design with OE ECU.
EFI LS main harnesses have a map sensor connecter designed for use with
an LS3 style map sensor. Adapter harness may be required to adapt any
LS harness that uses a LS1/2 MAP sensor connection to a LS3 MAP, which
is recommended for this manifold.
manifolds & fuel rails are designed to accept Bosch Style EV-1
or Magneti Marelli Pico fuel injectors (OE LS fuel injectors may not
fit properly in the intake manifold & fuel rail assembly).
