Dedicated Motorsports - 4.5" to 6" Billet Aluminum Velocity Stack
DMS 4.5" to 6" Billet Aluminum Velocity Stack – CNC Machined Intake Transition
Maximize airflow and performance with the DMS Billet Velocity Stack, designed to transition a 4.5” intake tube to a massive 6” air filter inlet with smooth, unrestricted flow. This is the same high-performance component featured in our CTS-V and Chevy SS cold air intake systems.
Key Features:
- Optimized Airflow – Designed for minimal turbulence and maximum efficiency.
- CNC Machined from Solid 6061 Aluminum – Precision built for strength and consistency.
- 4.5" Outlet to 6" Inlet – Perfect for high-flow applications that demand serious intake volume.
- Track-Tested Design – Proven results on forced induction and naturally aspirated builds.
Ideal For:
- Custom cold air intake systems
- LS/LT performance builds
- CTS-V, Chevy SS, and other GM performance platforms
Whether you're fabricating a custom intake or upgrading your current setup, the DMS 4.5" to 6" Velocity Stack delivers the smoothest transition for optimal airflow, throttle response, and horsepower gains.
