Info

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.

Holley Mid-Rise Intake for GM LS1/LS2/LS6 platform engines

  • 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).
  • 105MM EFI plenum top
