For greater weight reduction, PERRIN boost tubes are CNC mandrel bent from aluminum tubing. Every boost tube features an extra-large beaded end to guarantee the couplers and hose clamps stay attached and sealed! To transport air to and from the intercooler, they decide to follow the quickest, smoothest route possible. For a long-lasting, attractive finish that looks nice in any engine bay, tubes are available in either a Black or Red wrinkle powder coat. A smooth offset coupler immediately after the turbo transports the hot side air charge to an exactly matched 2.25 enhancer tube. The air charge is then routed through the engine bay next to the battery, down behind the radiator to the intercooler, and 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 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. All PERRIN intercooler kits come with PERRIN Performance silicone couplers as standard equipment. For long-lasting high strength and smooth air movement, PERRIN couplers are reinforced with fiberglass and have smooth inner walls. available in glossy red and black.
