Details:

PERRIN boost tubes are CNC mandrel bent from aluminum tubing for better weight reduction. Every boost tube has an oversized 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. Right off the turbo a smooth offset coupler carries the hot side air charge to a perfectly matched 2.25” boost tube. We chose 2.25" tubing for a smoother, cleaner, obstruction free routing while still being large enough to flow more WHP than most turbos can put out. The air charge then is routed through the engine bay next to the battery, and down behind the radiator to the intercooler. The cold side boost tubes are mounted as high as possible in the engine compartment to clear all turbo and intake combinations as it travels to the throttle body through the engine bay. The clamps included with the PERRIN FMIC are standard on all PERRIN intercooler kits. They are designed for uniform clamping at all points around the band. Never worry about having to re-tighten down the road, plus each PERRIN clamp is made in the USA and has the torque spec engraved on each one.
