Rubber is out and silicone is in for your 2015-2021 WRX! The Mishimoto silicone ancillary hose kit for the 2015+ Subaru WRX is designed to improve the reliability of your WRX and eliminate weak points found with the stock rubber hoses. We have carefully selected 12 hoses, both PCV and coolant lines, which we found can easily be replaced and benefit from the use of silicone. Mishimoto silicone hoses are crafted from four layers of silicone with heat-resistant embedded fibers to provide improved pressure and heat tolerance. PCV lines are commonly exposed to fine particles of oil which, over time, degrade the rubber and lead to eventual failure. Mishimoto silicone hoses have substantially greater resilience to these particles, providing a hose that will endure the test of time.

Each hose included in this 2015-2021 WRX kit is designed with stock specifications in mind, resulting in a direct-fit replacement that is easy to install. Whether you are entering your 2015-2021 WRX in the local rallycross, or lapping at your next track day, trust Mishimoto and our line of VA-chassis WRX parts to keep your car cool. This hose kit is available in black, blue, or red and, like our entire line of parts, includes the signature Mishimoto Lifetime Warranty.

Fits all 2015-2021 Subaru WRX.
