Holley LS1/LS2/LS6 Mid-Rise EFI Intake Manifold (HO300-127)

The Modular Mid-Rise intakeutilizes the popular Holley LS1/LS2/LS6 cathedral port Mid-Rise 2 x 4 intake manifoldalong 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-Risemanifold 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’sperfect for turbocharged, or normally aspirated applications.

This manifold is modular, and the plenum adapter (PN 300-231) will accept all of the popularHolley LS Hi-Ram plenum tops as a foundation for custom induction systems.

Features:

• Provides great performance to 6500 rpm for street/strip performance applications whileproviding the look of a racingEFI 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 withoutcompromising top end power
• Great for supercharged or turbocharged engines
• Power band from 1500-6500 rpm
• Mayrequire 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 OEECU).
