The factory rubber throttle body hose on the 2008+ Subaru WRX is prone to failure, especially on vehicles running increased boost pressures. The Mishimoto Silicone Throttle Body Hose provides increased pressure and heat tolerance, thanks to its 100% silicone construction. This hose features five layers of silicone with heat-resistant embedded fibers that withstand substantial boost pressure. The hose is equipped with a position indicator, making installation a breeze and possible in less than one hour. The Mishimoto Subaru WRX Silicone Throttle Body Hose is available in black, blue, or red.
