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.
