HOLLEY - 300-128 - $699.95
l92/ls3 style 105mm mid rise intake manifold
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 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 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.

Features:

  • 1500-6500RPM Power Band
  • 105MM EFI Plenum
  • Overall Height of 10.44 inches
  • Mid-Rise manifold for excellent street/strip performance
  • Fits GM LS3/L92 engines

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)
