PERRIN boost tubes are CNC mandrel bent from aluminum tubing for better weight reduction. Every boost tube has an over sized beaded end to ensure the hose clamps and couplers stay connected and sealed! We choose to take the smoothest shortest path to get air to and from the intercooler.

This FMIC Boost Tube Box comes with an offset coupler that directs the hot air charge from the turbo to a precisely-matched 2.25” boost tube. The tubing, large enough to support high WHP outputs, creates a free-flowing, streamlined path from the engine bay near the battery, down behind the radiator, to the intercooler. Additionally, the cold side boost tubes are fixed above the turbo and intake components in the engine compartment to ensure clearance to the throttle body.
