Details:

With boost tube diameters sized from 2.25” from the turbo to 2.75” from the intercooler to the throttle body, PERRIN Boost Tubes feature smooth routing while flowing more air than most turbos can produce. They are CNC mandrel bent from lightweight aluminum tubing and feature an oversized, beaded end to keep hoses secure and sealed at any boost level.

PERRIN Boost Tubes utilize the smoothest, shortest path to move air to and from the intercooler, all while maintaining clearance around OEM components. The result is an easier installation and unrestricted airflow for optimal engine performance.

PERRIN Boost Tubes are powder coated for protection from the elements, making them look awesome for years to come. Boost tubes for this kit come in three finish options, glossy neon yellow, or texture powder coated black and red.

This FMIC Kit includes a 6061 aluminum, high capacity washer fluid tank which provides extra space for proper boost tube routing.

This FMIC Kit includes a new PERRIN Coolant Overflow Tank adding clearance for boost tube routing. The PERRIN Coolant Overflow Tank is protected from the elements with a texture powder coating.

PERRIN CNC-machined, direct-mount intercooler brackets are made from lightweight aluminum and offer exceptional rigidity, corrosion resistance, and a clean, performance-focused appearance.
