Performance Design Carbon pTR Intake Manifolds

Performance Design Carbon pTR intake manifolds combine high-quality materials into a flexible and powerful tunnel ram architecture. PA6GF30 glass-reinforced nylon (lower) and 5-layer carbon fiber (upper) shells combine for lightweight, strong, and heat-resistant performance. Offering unique modular velocity stacks enabling 6 1/2 in. to 9 in. runners, multiple accessory port and sensor options along with other custom features, these high-performance manifolds offer easy configuring for a variety of hot rod builds, and can even be reversed on the engine.

The plenums feature high-strength carbon fiber with high-temperature epoxy for improved strength-to-weight ratio and reduced heat soak to the fresh air charge. The polymer lower runner pack resists heat soak from the cylinder heads and hides all the ports/sensors in the valley. This combination of materials offers a 10 lbs. weight savings over competitive aluminum tunnel ram manifolds. These custom assemblies are designed for resto-mod, off-road race trucks, race boats, and hot rods where hood clearance is not an issue (they will not fit under late model vehicle hoods).
