This Mishimoto top-mount intercooler kit fits 2002–2007 Subaru WRX and 2004–2007 STI models and uses a single-entry inlet to promote superior core airflow compared to the stock Y-pipe. The high-efficiency bar-and-plate core improves heat transfer and volume. The complete bolt-on kit includes silicone hoses, a bypass valve gasket, T-bolt clamps and installation hardware, and is validated to reduce intake temps and increase power up to 350 hp applications.
