Product Description
Performance Design Carbon HR Intake Manifold Lid for Holley Intakes
The Carbon HR Intake Manifold Lid offers owners of the Holley Hi-Ram, Mid-Ram and Lo-Ram intakes a lightweight carbon fiber plenum upper to reduce weight, reduce heat soak and add a unique look with exposed weave cloth. Constructed from high strength carbon fiber with high temp epoxy, bonded with high temp aerospace structural adhesive this part saves approximately 3 pounds vs the cast original lid.
With a matching plenum bolt pattern, this carbon plenum upper will bolt to any existing Holley Hi-Ram, Mid-Ram or Lo-Ram cast lowers. The throttle is moved up and rearward to improve the flow transition into the plenum and facilitate the carbon process.
Machined, molded and hand assembled in Michigan.
