Injen Intercooler pipes are the next logical step in your search for power gains. The Injen staff has put in the time and work to develop parts that perform. These Intercooler pipes are no different, after investigating the OE piping, our engineers identified numerous areas where improvement was necessary. The Injen performance intercooler pipes are constructed of mandrel-bent aluminum piping that eliminates the rust buildup present in the most stock pipes. Injen's Automotive Grade Silicone Couplers and Stainless Steel Band Clamp with Inner Protective Liner are also included in this kit. The Injen technology Silicone Couplers are on a new level. Compared to normal silicone, Injen Automotive Grade Silicone Couplers provide superior resistance to heat, pressure, fuel, and oil. This effectively increases the life of the couplers by preventing leaks and blowouts. The Injen Intercooler Pipe Kit is designed to work with the stock as well as the Injen performance intercooler*. This Intercooler pipe performance kit, like all of our Injen performance parts, includes the Injen Limited Lifetime Warranty.
