HKS Premier Suction Air Intake Funnel.
This item replaces the restrictive factory air resonator.
Even with the factory air box this item will give you a sporty sound.
It is more effective when used with a performance panel filter.
Warning: Please note that once this item has been fitted the inlet will be located about 350mm lower than factory air duct, caution must be taken when driving - if water enters the funnel it may cause engine failure.
Direct replacement for the Impreza WRX/STi GRB (Also fits GVF, GVB, GRF models).
