Stock plastic or rubber intercooler pipes can expand or crack under high boost levels. In addition to this, stock pipes have many bends which in some places are very tight radius which causes much resistance and pressure drop. HKS Piping kits are made of aluminum for increased durability and safety. The pipes have been redesigned to decrease the number of bends and to increase bend radius to minimize pressure loss and flow resistance.
