Performance Design 70515.07.00.XX - Carbon pTR - LS7 Manifold 105MM (Long Runners Installed)

The Carbon pTR Intake Manifold combines the best materials into a flexible and powerful tunnel ram architecture. Glass reinforced nylon lower and carbon fiber upper shell combine for lightweight, strong and heat resistant performance. Offering unique modular velocity stacks enabling 6.5 9 runners, multiple accessory port and sensor options along with other custom features, this manifold offers easy configuring for any LS3 or LS7 hot rod setup.

Shipping with the longer runner, optional velocity stacks offer different lengths. Tuning of the intake runner length to match the cam, head and exhaust combo gives the ultimate way to optimize your engines power curve. Shorter runners support high RPM drag applications or longer runners for improved torque in the mid-range. Mixing lengths can help smooth out the torque curve.

The plenum is constructed from high strength carbon fiber with high temp 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 heads and houses all ports/sensors hidden in the valley. The combination of materials offers a 10 lb weight savings over competitive aluminum tunnel ram manifolds.

**Does not fit underhood on late model vehicles; best suited for resto-mod, off-road race trucks, race boats and hot rods.**

These intakes are standard stock with red fuel rails. If you would like to order them in black or without fuel rails, please contact us!
