Holley EFI 300-304BK HI-RAM 95MM Cast Side Mount Plenum Top Black Finish

Not Available

Holley now has cast aluminum plenum top options for those of us with limited room in the front of the engine bay. This cast aluminum side mount plenum top resembles the older 5.0L EFI manifolds and will allow you to mount the throttle body on the side. This will allow for easier fabrication for boosted applications or for just a different look on your Hi-Ram manifold. This comes in cast aluminum construction with a black finish and is designed to mount on Holley's existing Hi-Ram manifold base.

Features:

  • Designed for side mounted throttle bodies
  • Allows room for designing boosted applications
  • Cast Aluminum construction
  • 95mm size
  • Compatible with GM® style throttle bodies up to 95mm
  • Mounts to existing Hi-Ram manifold bases
  • Lid has been verified to fit under Cervinis 2.5” cowl hood on 1979-1993 Mustangs with 351W & 302W Hi-Ram bases when using motor mounts that retain stock engine locations.
