Performance Design Carbon pTR Intake Manifold LS3 LS7

Performance Design Carbon pTR Intake Manifold LS3  LS7 Part #: 70515.07.BK & 70515.07.BK 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 engine’s 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
