The Mishimoto Top-Mount Intercooler Kit upgrades the 2002-2007 Subaru WRX and 2004-2007 STi charge-air system with a bolt-on, single-inlet bar-and-plate core that replaces the restrictive stock Y-pipe setup. On a 305 HP test car at 20-22 psi it added 14 HP and dropped AITs 30F versus the stock STi unit, and it supports builds up to 350 HP. The kit installs with zero vehicle modifications and includes silicone bypass hoses for WRX and STi, a crankcase ventilation hose, throttle body hose, bypass valve gasket, and all T-bolt clamps and hardware. Finished in stealth black powder coat with red silicone hoses.
