Description
The Mishimoto Silicone Ancillary Hose Kit (MMHOSE-WRX-15ANCBL) is a specific-fit Fabrication upgrade built for the Subaru WRX, replacing twelve factory rubber PCV and coolant hoses with direct-fit silicone lines engineered to factory specifications. Offered here in blue, this kit targets the weakest rubber lines in the WRX engine bay, swapping them for four-layer silicone hoses reinforced with heat-resistant embedded fibers to combat the oil-exposure issues that shorten the life of stock PCV lines.
Because PCV hoses are constantly exposed to fine oil particles, factory rubber lines tend to harden and fail well before other engine components wear out. Mishimoto’s silicone Fabrication hose kit was developed to resist that degradation while also tolerating greater heat and pressure than the stock rubber it replaces, improving overall longevity and reliability. Every hose in the kit is molded to factory specifications for a true direct-fit replacement, so installation follows the same routing as the original equipment without modification. As a performance-grade silicone product from Mishimoto, this kit gives WRX owners a straightforward way to upgrade a commonly overlooked failure point in the engine bay.
