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! They choose to take the smoothest shortest path to get air to and from the intercooler. Tubes are available in a Black or Red wrinkle powder coat for a long lasting durable finish that looks good in any engine bay.
Right off the turbo a smooth offset coupler carries the hot side air charge to a perfectly matched 2.25” boost tube. PERRIN 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.
PERRIN Performance silicone couplers are standard with PERRIN intercooler kits. PERRIN couplers are fiberglass fortified with smooth inner walls for long lasting high strength and smooth air flow. Available in glossy black and red.
PERRIN Performance T-bolt clamps are standard on PERRIN intercoolers. They are designed for uniform clamping at all points around the band. The wider band distributes the force over a larger area and the fine threaded bolts with nylon lock nuts allow for accurate torque and proper clamping. Never worry about having to re-tighten down the road, plus each PERRIN logo-ed clamp is made in the USA and has the torque spec engraved on each one. Advantage PERRIN!
The PERRIN front mount intercooler kit includes a PERRIN Performance coolant overflow tank. It adds clearance for better boost tube routing, holds more coolant than previous designs and uses the OEM tank cap for a great seal! The PERRIN Performance coolant overflow tank is protected from the elements by a black texture powder coating. It looks great and makes the silk screened logo pop.
This boost tube kit is only for use with PERRIN front mount intercoolers.
