Boost Tubes And Couplers

The kit includes a smooth offset coupler and perfectly matched 2.25” boost tube for optimal airflow. With a larger diameter, these tubes ensure a smoother, cleaner path for air to flow, maximizing horsepower.

Efficient Cooling Design

The hot side air charge is efficiently routed through the engine bay, next to the battery, and down behind the radiator to the intercooler. The cold side boost tubes are strategically mounted high in the engine compartment, ensuring clearance for various turbo and intake setups.

Coolant Overflow Tank

As a bonus, the PERRIN Boost Tube Kit includes a PERRIN Washer Fluid Tank and a PERRIN Coolant Overflow Tank. These tanks are both protected by black powder coating, adding durability and style to your engine bay.

Premium Construction

Crafted from CNC mandrel bent aluminum tubing, PERRIN Boost Tubes are lightweight yet strong. Each tube features an oversized beaded end to ensure secure connections and prevent leaks.

Powder Coat Finish

To withstand the elements, every PERRIN Boost Tube is powder coated, coming in black finish. Upgrade your STI with PERRIN and experience optimal performance with style that lasts for years to come!
