Performance Design Carbon HR Intake Manifold Lids

Performance Design Carbon HR intake manifold lids offer owners of the Holley Ram intake models a lightweight. carbon fiber plenum upper. These top sections reduce weight, reduce heat soak, and add a unique engine aesthetic with the exposed weave cloth. Constructed from high-strength carbon fiber with high-temperature epoxy and bonded with high-temperature aerospace structural adhesive, each unit saves approximately 3 lbs. of mass versus the cast original lid. With a matching bolt pattern, the carbon plenum uppers will bolt to any existing Holley Hi-Ram, Mid-Ram, or Lo-Ram cast lowers. The throttle is moved up and rear-ward to improve the flow transition into the plenum and facilitate the carbon process. Order the model designed for your application needs. Other product features and specifications include: * Billet throttle body flange (90-105mm) * Plenum can be reversed on the Holley Ram lower * Carbon fiber-wrapped foam core plenum flange Show Less
