Bellmouth Velocity Stack Aluminum 3.5In Inlet O.D

The Bellmouth Velocity Stack Aluminum 3.5In Inlet O.D. from VIBRANT PERFORMANCE is a precision intake manifold component designed for performance engine builders seeking to maximize volumetric efficiency. This velocity stack is particularly beneficial for those constructing custom intake systems, channeling ambient air into the engine with minimal turbulence and flow restriction.

Constructed from lightweight aluminum, this 3.5-inch inlet diameter component features a precision-engineered bellmouth design that transitions smoothly from the intake runner into the combustion chamber environment. The bellmouth geometry reduces flow separation and turbulence at the valve seat, allowing air molecules to enter with optimized velocity and minimal energy loss. Weighing just 0.34 lbs, it adds negligible weight while its compact dimensions integrate seamlessly into most custom intake manifold configurations.

This velocity stack is ideal for performance engine builds, providing measurable gains in throttle response and mid-range torque delivery. Engine builders and tuners looking to refine their intake systems will find this product enhances overall performance, making it a valuable addition to any high-performance setup.
