Mishimoto has developed the Subaru WRX silicone ancillary hose kit as a direct OEM replacement fit. Made with a dual layer combining high grade silicone and heat-resistant embedded fibers to provide efficient heat reduction and increased pressure tolerance. Choose from red, blue, or black color.
Fits all 2006-2007 WRX and 2004-2007 STI. Note: The bottom expansion tank hose will not fit 2004-2005 STI models, due to a larger port size.
