The Mishimoto top-mount intercooler for 2002–2007 Subaru WRX and 2004–2007 STI replaces the stock Y-pipe with a single-entry inlet for smoother airflow and better dispersion through a high-efficiency bar-and-plate core. This bolt-on kit includes silicone bypass and crankcase hoses, a throttle-body hose, bypass valve gasket, T-bolt clamps and hardware. Validated in testing to lower intake temps and increase power, supporting up to 350 hp.
