The PERRIN Boost Tube Kit has been crafted to work specifically with the PERRIN Front Mount Intercooler. These have been carefully crafted from CNC mandrel Bent Aluminum piping, and designed with oversized beaded ends to make sure those hose clamps stay put. Additionally, the smooth bends in the piping promote a smoother air transition in boost pressure. The piping size measures at 2.25”, and the routing of the pipes are bent nicely around the contours of the engine bay to make for a great fitment for the stock turbo location. Furthermore, the piping has been powder-coated with a finish that can withstand the heat, and will be protected from corrosion. Best of all, your engine bay will greatly be enhanced. Included with this boost tube kit are the intercooler piping, PERRIN black silicone couplers with a white PERRIN Logo.

Tubes are available in a Black or Red wrinkle powder coat for a long lasting durable finish that looks good in any engine bay. PERRIN silicone couplers are fiberglass fortified with smooth inner walls for long lasting high strength and smooth air flow.
