Holley EFI Mid-Rise Intake - GM LS1/LS2/LS6 w/ 105mm Top - Part# 300-127
Holley Mid-Rise Intake for GM LS1/LS2/LS6 platform engines
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 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 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.
*** 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.
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
