HKS Premium Suction Kit Subaru Impreza

• Stock rubber hose is replaced with aluminum pipe.
• The specially designed polished aluminum pipe improves engine compartment appearance.
• No affect to stock management system. 

   

Airflow meter does not show fluctuation with or without  Premium Suction. (See the graph on the  left.) However,  the intake resistance is reduced when Premium Suction  is installed. (See the red line on the  graph on the right.)  Unique design of the pipe connected to the turbine and  aluminum suction pipes can reduce the intake resistance.  Experience the improved engine response when  accelerating for overtaking.
