Carbon XR - LS7 Intake Manifold 87/90mm

4-Bolt Gen IV DBW

**Please call for pricing and options.**

Built for torque with long runner lengths, the Carbon XR is a cross-ram architecture intake manifold constructed of carbon fiber and billet 6061-T6 aluminum. A 5-Axis CNC machined head flange offers perfect port matching to the head entrance. Carbon fiber runners are constructed using high temp pre-preg manufacture with braided sock resulting in no seams or ply drops throughout the part for ultimate strength. The plenums employ a high temp resin infusion manufacturing process for consistent wall and beautiful finish out of the mold with an internal core for rigidity.
