While the factory intercooler piping is sufficient for stock horsepower levels, it is pertinent to upgrade to a hard pipe kit. The benefits of switching from the factory rubber hose over the engine to a hard pipe kit is two fold. One is to aid in the turbochargers efficiency; every bit of boost used to swell a rubber tube means you have to run the turbocharger at a higher boost pressure to make the desired horsepower. Two is to assist the engines response in a boost recovery situation (between shifts). The combination of these items result in faster spool up and more horsepower throughout the rpm band. The hardpipe kit includes T-Bolt Clamps, Black Silicone Couplers and Mirror Polished 2.5 inch mandrel bent piping
