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.
