Product Description

The Vibrant Performance 10954 aluminum bellmouth velocity stack is a precision-formed induction component engineered to enhance airflow into the intake tract or turbocharger on custom and performance builds. Crafted from spun T6061 aluminum with a large 8.75" bellmouth opening, this stack promotes smoother air entry and reduced turbulence, which can improve engine breathing and throttle response in naturally aspirated or forced induction applications.

With a 5.00" inlet outer diameter, the 10954 fits common intake tubes and adapters used in custom intake systems. Though universal in design and requiring fabrication, its large bellmouth design helps reduce turbo lag and optimize volumetric efficiency in high-performance engines, making it a popular choice for race applications, street builds, and turbo projects.
