Vibrant Performance 10953 Aluminum Velocity Stack with Bellmouth, 4-Inch Inlet and 7-Inch Outlet

Improve airflow into your intake system with the Vibrant Performance 10953 Velocity Stack. Designed with a bellmouth profile, this aluminum air inlet component helps guide air smoothly into compatible intake tubing, supporting efficient airflow and a clean, purposeful installation. Its 4-inch inlet and 7-inch bellmouth outlet provide a practical configuration for custom intake systems, motorsport applications, and performance-focused fabrication projects.
The lightweight aluminum construction offers a balance of strength, durability, and reduced system weight. The natural aluminum finish provides a clean appearance and can be used as-is or incorporated into a customized intake assembly. This velocity stack is supplied as an individual component, making it suitable for builders who need a reliable bellmouth inlet for a new installation or replacement application.
The Vibrant Performance 10953 is intended for applications requiring a 4-inch outside-diameter inlet and a 7-inch outside-diameter bellmouth. Verify clearance, mounting requirements, and compatibility with the surrounding intake components before installation. As a non-restricted air component, it is designed for use in systems where unrestricted intake airflow is desired. Professional installation and appropriate fabrication practices are recommended for the best fit and performance.
