The PERRIN Boost Tubes are CNC mandrel-bent from lightweight aluminum and engineered with a smooth, shortest-path routing design to maximize airflow and minimize restriction. With tubing diameters transitioning from 2.25” at the turbo to 2.75” at the throttle body, the system supports airflow levels beyond what most turbochargers can produce.

Each tube features oversized beaded ends to ensure a secure, leak-free seal under high boost conditions. Available in textured black or red powder-coated finishes, these boost tubes offer both durability and style.
