Stock plastic or rubber intercooler pipes can expand or crack under increased 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 aluminium for increased durability and safety. The pipes have been redesigned to decrease the number of bends and to increase bend radius to minimise pressure loss and flow resistance.
Special Piping Kit
A special kit made for GT-R models. GT-R have front mount intercooler as stock and with the addition of this kit, both performance and appearance is improved.
full Piping Kit
This kit comprises of intercooler piping and suction piping kits. This is the ideal kit for cars tuned using the stock intercooler. Suction pipe (between air cleaner and turbo) will also improve performance and accents the engine bay.
Intercooler Piping Kit
Piping kit which replaces the pipes from the turbocharger to intercooler and the intercooler to inlet manifold. A convenient kit which allows the replacement of boost pipes which can frequently pop off in higher boost use and is recommended for tuning where the stock intercooler is still used.
Suction Piping Kit
Piping kit which replaces the stock pipes between the air cleaner and turbocharger. Stock suction pipes can often become compressed or crushed. These aluminium pipe kits prevent this to increase intake air flow efficiency.
