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.
Replacing the rubber inlet & outlet hoses with aluminum hoses restrains its expansion to improve the throttle response and smoothly increase the boost pressure. Also, aluminum hoses can be securely connected even under a high pressure.
Factory rubber hoses are replaced with aluminum pipes and silicone joint hoses, and they are secured with reinforced hose bands.
HKS original casting inlet pipe allows smooth layout.
