Holley EFI GM LS3/L92 Mid-Rise Intake w/ 95mm Top - Black

The Modular Mid-Rise intake utilizes the popular Holley LS3/L92 rectangle port Mid-Rise intake manifold along with a purpose built plenum base adapter and a Holley 95MM 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 power band from 1,500-6,500 RPM and limited hood clearance. It's perfect for turbocharged, or naturally 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.

Recalibration of the ECU may be required when using this intake manifold design with OE ECU.

Holley EFI LS main harnesses have a map sensor connecter designed for use with an LS1/2 style map sensor. The 558-416 is an adapter harness that can be used to adapt any LS harness that uses a LS1/2 MAP sensor connection to a LS3 MAP, which is recommended for this manifold. 

NOTE: these 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).

*** 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.
