Performance Design XR Carbon Fiber Intake Manifold - Crossram LS3 LS7


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.

• Runner length: 12.5”
• Bell mouth entrance: 2.75” effective dia.
• Dual 90mm throttle, GM 4 bolt
• Plenum volume: 7.2L each, 14.4L combined
• Height: 11.6" from block valley surface
• Accepts USCAR EV6 body fuel injectors such as LS7/LS3 production/aftermarket
• (LS9/LSA injectors have targeted spray patterns and are not recommended)
• Intake can be reversed on the engine
• Works with moderate boost (rated to 25psi); can be specially built for higher boost levels
