The HKS Racing Suction Kit uses knowledge and technology gained from its close relative the Super Power Flow, but has improved upon it dramatically. The HKS Racing Suction Kit utilises the same power flow head as the Super Power Flow Kit, which maximises performance, mainly due to the unique internal funnel design. This creates a controlled vacuum that draws air from the outer edges of the filter increasing airflow and performance. Air taken in from the intake is directed to the engine with minimum resistance aimed at giving maximum intake efficiency within the limited space available in the engine bay. Standard factory pipes can cause massive turbulence in the intake system because they are usually made with convoluted piping. The aluminium pipes within the HKS kit improve engine response by creating a smooth undisturbed flow of air. The HKS Racing Suction Kit not only improves on power but also looks great in the engine bay.
