Description

The Modular Mid-Rise intake utilizes the popular Holley LS1/LS2/LS6 cathedral port Mid-Rise 2 x 4 intake manifold along with a plenum base adapter and a Holley 92MM EFI plenum top which converts it into a Mid-Rise EFI intake manifold.

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

Features & 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).
