Blox Velocity Stack 3" Aluminum

The Blox Velocity Stacks are designed to optimize and maximize air flow rates entering the induction system.

Velocity Stack is a trumpet-shaped device that are fitted to the air entry of an engine's intake system, carburetor or turbo air inlet.

Allow smooth and even entry of air at high velocities into the intake tract with the flow stream adhering to the pipe walls.[citation needed]

Modify the dynamic tuning range of the intake tract by functioning as a resonating pipe which can adjust the frequency of pressure pulses, based on its length, within the tract.
