The turbocharger not only generates pressure, but also generates heat in the process. Once the sum of heat and pressure exceeds the level that the plastic intercooler pipe can withstand, it will rupture. Therefore, aluminum alloy pipes are used for upgrading.
Silver Pipe: Constructed of mandrel-bent aluminum with a polished finish. A 100% CNC-machined 6061 aluminum coupling allows you to retain your trucks factory emissions components and allows for a quick install.
Silicone Connection Tube: Triple Reinforced Silicone Able to Withstand High Heat and Pressure, Will Reduce Vibration Transfer Due to Hard Impact Shifting or Engine movement
