Product Information

HOLLEY – LS SINGLE-PLANE MID-RISE EFI INTAKE MANIFOLDS

These lightweight, cast aluminum, single-plane intake manifolds from Holley feature optimized runners to help your LS engine produce a power band that starts at 2500 and runs up to 7000 RPM. And because of their mid-rise height and low carb flange placement, hood clearance won’t be a problem in most cases. Holley built their excellent reputation on over 100 years of experience, which is why they’re one of the leaders in fuel delivery systems and the choice of every NASCAR team for the past four decades.

  • Cast aluminum and lightweight
  • Low carburetor flange height for hood clearance
  • Wide power band, from 2500-7000 RPM
  • Runner layout is optimized for air flow
  • Fits 4150 bore flanges
  • Manifolds for rectangular or cathedral port heads
