The 2.5L Subaru WRX & STI uses engine coolant to heat up the throttle body. The hoses that connect to the throttle body can get old and start to leak. Freshen them up with factory-new OEM Subaru parts.
Inlet and outlet hoses to the throttle boy are the same on this car so if you need both order two.
Fits all 2006-2007 Subaru WRX & 2006-2021 STI
