Performance Design Velocity Stacks

Performance Design Carbon pTR intake manifold features modular, interchangeable velocity stacks to fine-tune the intake to your specific application, and includes long 9.0 in. runner stacks by default. However, they conveniently offer the long velocity stacks separately, along with medium 8.0 in. and short 6.5 in. runner size options. Performance Design Carbon pTR velocity stacks also fit FAST LSXHR intake manifolds. Select the stacks in the runner length wanted to tune your manifold to your specific needs.
