Installation Tips

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 exposed to UV over longer periods, it is recommended that an automotive clearcoat be applied to the carbon fiber. This can be done by any automotive body shop using standard painting methods. In addition, anodized components are more affected by UV exposure.

Our carbon fiber components receive a final polish before putting them in the box. However, over time the luster can be reduced. To easily return your product to peak shine, use Meguiar's PlastX polish and a microfiber to bring back a deep shine.

Details

The Carbon LS1/LS2/LS6 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.
