4″ Black Short Turbo Aluminum Velocity Stack




Velocity Stack is designed to optimize volume tric flow rates into your induction system by preventing boundary layer separation at the inlet of your induction system.
Traditional induction systems utilize a filter or filtration system that creates unfavorable geometry that initiates turbulent vortices and eddies at the inlet of your induction system, reducing the air flow effectiveness.
Velocity Stacks take advantage of the large flanged filter to create a induction system inlet geometry that will eliminate this “choke plate”, by preventing the boundary layer separation and resulting turbulence. Specifics & Features
