Mishimoto Subaru 15-21 WRX - Black Silicone Radiator Coolant Ancillary Hose Kit


Sale price Price PRICE: $154.95 Regular price $256.77 Unit price  per 

The Mishimoto Silicone Ancillary Hose Kit for the 2015+ Subaru WRX is designed to improve the reliability of your vehicle and eliminate weak points found with the factory rubber hoses. We have carefully selected 13 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 kit is designed with factory specifications in mind, resulting in a direct-fit replacement that is easy to install. This kit is available in black, blue, and red and includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.
