The Mishimoto Ancillary Hose Kit for 2015+ Subaru WRX contains thirteen PCV and coolant lines chosen as direct-fit replacements to replace vulnerable factory rubber hoses. Each hose uses four layers of silicone with heat-resistant embedded fibers to improve tolerance to heat, pressure and oil exposure. The kit is available in blue, installs to factory specifications as a direct-fit set, and includes Mishimoto's Lifetime Warranty.
