The Process West Charge Pipe Kit for the 2015+ Subaru WRX, is the best upgrade charge pipe kit on the market. Made in 2 pieces it is easy install, without the hassle of trying to feed one big pipe into position and includes all the necessary couplers and clamps for the perfect fitment. The charge pipe kit provides a much smoother air flow path from the turbo to the intercooler, over the factory pipe. Finished in a nice black powdercoat, the upgrade doesn't look out of place, and gives a factory appearance.
