The factory intake duct is only to connect the air intake boots to the turbocharger. HKS Carbon Suction Piping Kit was designed to improve the turbocharger’s intake efficiency by reducing the suction resistance. Also, when the boost pressure smoothly increases, the engine output at the low RPM can be improved, and the boost pressure at high RPM can be stabilized; therefore, the engine output at high RPM can be improved. This piping kit is made of Carbon that can improve the engine compartment appearance. Also, this kit can improve performance for the vehicle with the factory turbocharger to the one with Sport Turbine Kit.
* If the boost pressure is increased with the boost controller such as HKS EVC, the engine computer resetting may be necessary.
