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 cathedral port 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 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.

The best intake on the market hands down
From Anonymous of Blue springs, Missouri on .
Gains over the tbss and lsxr ! Not any lower end torque loss first ran on n/a 6.0 now on boosted 6.0 .Looks amazing and not the same as all the others at cruise night. Now if only they had a mid mount air to water intercooler???

Carbon fiber exposed to UV will exhibit some resin yellowing over time. While our experience has been that in most cases the changes over time has been less than expected, in some cases with more exposure this is accelerated. If your application will be
