The Mishimoto Ancillary Hose Kit for 2015+ Subaru WRX contains thirteen PCV and coolant lines selected as direct-fit replacements to address weak points in factory rubber hoses. Constructed from four layers of silicone with heat-resistant embedded fibers, these hoses resist heat, pressure and oil degradation better than stock rubber. The kit fits as a direct replacement, is available in black, blue or red, and includes Mishimoto's Lifetime Warranty.
