Description

Holley EFI intake manifolds feature port-matched upper and lower runners for reduced restrictions. Plus, the EGR passages have been relocated to the outside of the manifold to allow for the use of larger intake ports. The result is greater air capacity, which makes these manifolds the perfect choice for supercharged engines. They're available in a variety of styles and options; select the model designed for your vehicle and/or engine application.
