PERRIN Front Mount Intercooler Boost Tube Kit Red Subaru STI 2008-2014 | PSP-ITR-430-3RD

Product Fitment: 

2008-2014 Subaru STI

This kit includes a PERRIN Coolant Overflow Tank, which creates additional space in the engine bay for proper boost tube routing. Finished in a durable textured powder coating, the tank is built to withstand harsh under-hood conditions while maintaining a clean, long-lasting appearance.

At the heart of the system are the PERRIN Boost Tubes, designed to provide the smoothest and shortest airflow path possible. With tubing diameters transitioning from 2.25” at the turbo to 2.75” at the throttle body, these pipes support increased airflow capacity—ideal for high-performance and upgraded turbo setups.

Constructed from lightweight CNC mandrel-bent aluminum, the boost tubes ensure maximum strength while minimizing restriction. Each tube features oversized beaded ends to keep couplers secure and sealed, even under high boost pressure.

To enhance durability and aesthetics, the boost tubes are finished with a protective powder coating, available in textured black or red, ensuring long-lasting performance and a clean engine bay look.
