Straight fin cooling effect for 184～320kw (250～450PS) light tuning.
Front mount intercooler kit with S-type core. New S-type core was developed only for GDB kit in order to improve response. Because front mount layout usually has a demerit of slow response. Pipe layout is designed as straight and short as possible. It enabled as quick boost response as stock intercooler. When a vehicle is stopped, stock top mount intercooler core keeps heat inside from the engine compartment and then, when the car starts, sometimes knocking occurs. Front mount intercooler decreases intake air temperature and it enables safe and reliable tuning. Front bumper and reinforcement needs to be modified. It is not possible to install stock fog Lamp and recirculation valve. (Installation of HKS Super SQV is recommended.) It is possible to use with HKS Oil Cooler Kit (for applied model E 15004-AF006, for applied model F 15004-AF007). Modification of air guide is required. It does not fit to STI SPEC C (with Transmission Cooler, Engine Oil Cooler).
