Holley EFI LS Single Plane Mid-Rise Intake Manifolds #300-269

If you have a high horsepower engine, the Holley EFI LS single plane mid-rise intake manifolds are a great choice. These manifolds have a durable cast aluminum construction and are suitable for use with centrifugal blowers, turbos, or mild NOS power adders. The lightweight design, at only 11.5 lbs, features consistent wall thickness and sturdy mounting flanges. With an optimized runner layout and constant cross sectional area, these manifolds deliver a wide torque curve and exceptional performance from 2,500 to 7,000 rpm. Additionally, the mid-rise design offers a low carb mounting flange height without sacrificing power, making it ideal for vehicles with limited hood modifications. Each intake manifold also comes with zinc-plated hex head cap mounting bolts and washers, pipe plugs for blocking vacuum and MAP sensor ports, and Viton® O-ring cylinder head mounting flange gaskets for a reliable OEM-style seal.
