Description
The Mishimoto Ancillary Hose Kit (MMHOSE-WRX-15ANCRD) is a red silicone hose kit purpose-built for the 2015+ Subaru WRX, replacing twelve factory rubber PCV and coolant hoses with a direct-fit silicone alternative. As part of Mishimoto’s Fabrication lineup, each hose is engineered to factory specifications, so this kit drops in without modification while addressing a well-known weak point in the WRX’s factory rubber hose routing.
Built from four layers of silicone reinforced with heat-resistant embedded fibers, this Performance-grade hose kit offers greater tolerance to heat, pressure, and oil degradation than the stock rubber hoses it replaces. PCV lines in particular are constantly exposed to fine oil particles that break down rubber over time, and Mishimoto’s silicone hoses are built to resist that degradation, helping the ancillary hose kit deliver long-term reliability across the WRX’s PCV and coolant hose circuit. Because it’s a vehicle-specific rather than universal-fit product, this Mishimoto silicone hose kit is designed to bolt directly into place, improving both the longevity and reliability of the ancillary hose system.
Vehicle Applications
This is a specific-fit kit engineered for the Subaru WRX rather than a universal hose kit. Coverage spans the WRX Base, Limited, and Premium trims from 2015 through 2021, the Sport and Sport-tech trims from 2017 through 2021, and 6-speed manual and CVT-equipped WRX models from 2018 through 2021. It also fits the Sport-tech RS trim for 2019 and 2020, the 2019 Raui Edition, and the 2021 WRX EyeSight trim.
